Discussion Overview

The discussion revolves around unusual mouse behavior on a Windows 7 laptop, including issues with mouse functionality on the desktop and taskbar, erratic scrolling in Firefox, and potential hardware problems. Participants explore various troubleshooting steps and hypotheses regarding the cause of the issues.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • The original poster describes intermittent mouse functionality where actions work on either the desktop or taskbar, but not both.
  • Some participants inquire about the type of mouse and keyboard (wired or wireless) and suggest testing in safe mode or using a live-linux CD.
  • One participant suggests that restarting the computer may resolve the issue, citing it as a common fix for similar problems.
  • Concerns are raised about the reliability of the keyboard, with suggestions that a loose cable might be the cause of the issues.
  • A participant identifies a feature called caret browsing in Firefox, suggesting it could be turned off with the F7 key, and mentions that the address bar issue might be related to an add-on.
  • The original poster notes that the erratic behavior occurs even before a browser is opened, indicating a potential operating system issue rather than a browser-specific one.
  • Another participant suggests checking the Control Panel's Ease of Access Center for any features that may have been inadvertently activated.
  • The original poster expresses suspicion that the problems may be hardware-related, given other issues with the laptop.
  • One participant speculates that the motherboard might be failing due to multiple hardware issues experienced by the original poster.
  • Another participant shares personal experiences with similar mouse issues being resolved by replacing the mouse.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the cause of the mouse issues, with multiple competing views regarding potential hardware failures, software settings, and the effectiveness of various troubleshooting steps.

Contextual Notes

The discussion highlights limitations in diagnosing the problem without further testing, such as using a different mouse or booting into safe mode. There are also unresolved questions about the interaction between hardware and software settings.

My laptop has been driving me nuts for the past 28 hours. Weird things are happening when I try to use the mouse. For example, when I've just logged in (Windows 7), the mouse is always in one of these two modes:

1. Mouse actions work on the desktop, but not on the taskbar.
2. Mouse actions work on the taskbar, but not on the desktop.

I can occasionally switch from mode 1 to mode 2 by clicking on the taskbar, and I can occasionally switch from mode 2 to mode 1 by clicking on the desktop, but most of the time, I'm just unable to switch.

Things get more weird if I open browser. Typically the mouse only works inside the tabs. I can open and close tabs. I can type things in an input field on the active tab (after I've clicked inside it). I can't type anything in the address bar. I can't do things like move or resize the window. The only way to close the window is to close all the tabs.

Occasionally, the computer appears to be thinking that I'm trying to drag something somewhere, when I have only clicked on a button or icon once and then moved the mouse away. This has happened both in a browser and on the taskbar.

In Firefox, some weird alternative scrolling feature is often activated even though I haven't done anything to make this happen. The location of the mouse pointer determines the direction and speed of the scrolling. For example, if I want to scroll down, I just hold the pointer below this thing

when it shows up. If I want to scroll faster, I just move the mouse pointer down a bit and leave it there. Of course, I don't want to use this feature at all. I have no idea why it's switched on.

I have tried obvious things like "turning it off and then on again". I tried uninstalling the mouse drivers and rebooted.

Around the time when this started, I was having difficulties pushing down the 7 key. I vacuumed the keyboard and it seemed to solve the problem. But I at least considered the possibility that my current problem is related to this one. I thought that maybe the computer thinks that a key is being held down constantly, and that this is interfering with the operation of the mouse. But I ran some testing software that tells me what key is being held down, and I didn't find anything odd.

If I just unplug the mouse and then try to use the touchpad, it behaves equally weird. The only way I know to stop the weird behavior is to unplug the mouse and reboot. When I log in again (mouse still unplugged), the touchpad is behaving OK.

I don't really expect anyone to be able to tell me what's wrong and how to fix it, but I figured I should at least ask.

I don't have another mouse that I can try. Maybe I'll buy one tomorrow.

Are your mouse and keyboard wired or wireless?

What happens in safe mode?
What happens when you boot up a live-linux CD?

What happens if you are not connected to the internet?
 
Restart. Fixes an embarrassment of gremlins like this.
 
Do all of your keys work reliably?
If not, you might have a loose cable inside that needs to be reseated.

This is called caret browsing - turn it off with the F7 key.

The address bar problem could be due to an Add-On. See this article - https://support.mozilla.org/en-US/questions/1038193.

For the rest, I would double check your mouse settings (Control Panel -> Mouse). It sounds like some of may have been reset.
I would also look around in the Firefox advanced settings for any odd.

It's a laptop, so I'm using the laptop's own keyboard. The mouse is wired. It's plugged into one of the USB ports. I've been having some issues with USB ports on this computer before (never with this one though), so I tried to move the mouse to one of the others. It made no difference.

I haven't tried safe mode yet. I'll try that now. Preparing a linux CD sounds like more work than just buying a new mouse.

That was obviously the first thing I tried.

They do. I downloaded some software to test them.

The F7 tip may come in handy. I don't think an add-on is the issue. I have similar problems (or the same problem) in different browsers. It's more like the operating system (or something) divides all the stuff on the screen into areas, and only one area at a time can handle mouse actions. When I can click the tabs, I can't click on anything on the background or on the taskbar. When I can click on things on the taskbar, I can't click on anything in the browser window. I have checked the settings now, and they look fine to me.
 
Could you list your OS and browser versions?
 
Another place that I would check is Control Panel -> Ease of Access Center. Some of those features can get turned on when certain keys are held for a long time. Make sure that the ones related to mouse actions are turned off.
 
Windows 7 Home Premium, Service Pack 1, 64-bit version.

Firefox 37.0.1 (this is the one I use)
Chrome 41.0.2272.118 m (wow, I thought Firefox's version number was ridiculous)

I haven't tried using Internet Explorer when the mouse is acting up. Note that the erratic behavior starts as soon as the operating system has been booted, before I have even had time to start a browser.

I had a quick look at the ease of access settings. I don't see anything odd there. I doubt that this is something as simple as a setting that has been set to a non-default value. For example, the caret browsing feature isn't just "on". It seems to get switched on at random. Same thing with the ClickLock feature (drag without holding down the mouse button). It's off in the configuration, but sometimes the computer is acting as if it thinks I want to drag the thing I just clicked.

Since I've been having so many hardware problems with this laptop (the wireless card is dead, the USB ports don't always recognize my memory sticks, the audio system is malfunctioning), I'm thinking that this may be a hardware issue too.

I'm not as familiar with hardware issues but if you're having that many issues, I would think that the motherboard was failing. :oldfrown:

If everything seems OK other than when using the mouse, maybe you could just borrow another mouse and see if the problem goes away.
I've certainly had one case of a weirdly behaving mouse, and a new 5 euro mouse turned out to be the solution.
Another time I discovered a similar problem it turned out that my 'alt' key was sticking, though it didn't look visually to be stuck.
You say that you've tested for that possibility though, so it probably doesn't apply for this case.

Thanks everyone who took some time to think about this. I'll buy a new mouse tomorrow to see if it works better.

That's why checking with a Live Linux CD might be good.
If it still fails, it's hardware. If not, then it's Windows.
