I'm not sure if this is really a bug with the forum software as opposed to some incompatibility with my browser, but whenever I load the forums for the first time after booting up my computer, any page with latex on it will freeze my computer, sometimes for over a minute, while the latex plugin(?) loads.

Has anyone else encountered this issue, and is there a fix or way to load the math plugin more smoothly so that it doesn't freeze up everything while it loads? I would really love to be able to keep using my laptop while the browser renders the math.

I'm using Chrome and running Windows 7 when this occurs. If I boot up into Ubuntu instead, I do not encounter the same problem with Firefox.

Any suggestions?

Thanks.

 Recognitions: Homework Help What makes you suspect that the $\LaTeX$ is the culprit? My first guess would have been a malicious, or just poorly written script in one of the ads on the site. Which could also explain why Greg isn't having anyproblems, as I doubt he sees the same ads we do.

I'll add the obvious suggestion: contribute to PF, and no more ads. Better experience all around.

 Blog Entries: 1 Recognitions: Gold Member Hmm. This sounds a lot like a freeze that I experience also. One freeze after I've started the computer and then it doesn't happen again. I'll have to see if it's occurring during a LaTeX load. I have Win7 w/ Firefox 3.6.16 - yes, I know it's ancient.

It happens with my home laptop the same way. Once it goes through one freeze-up it's fine after that. I run Chrome.

I seem to remember this being reported in the past...or am I imagining it ?

I sometimes get a message but it flashes up so quickly it's not readable.

Not that I'm aware of. There are no pop-up messages or anything, at least. The system just hangs up for a minute or so.

The system only freezes up when I load a page with TeX on it. If I start up my laptop and load PF and I browse, say, the Career services forum first, nothing freezes. It's only once I go to a page with rendered LaTeX that it locks up. If I go to a math forum and there's a title with latex in it, everything freezes; if there are no titles with Latex in them, then the system only locks up once I go into a thread with the LaTeX.

Also, this only happens once following booting up the computer. Even if I close the browser entirely and come back it won't freeze up again.

So, for these reasons I believe it is my browser loading the math the first time that is the issue.

To be honest I don't mind (or notice) ads very much, unless they start taking up the whole screen or talking, which I don't think has happened on PF. In any event, I don't suspect it's the ads causing a problem. However, it is probably about time I contributed...

At least I'm not the only one!

Where does the message show up? I haven't noticed one before, but maybe I'm always just looking somewhere else when the system freezes. Also, I am using a laptop as well... I don't know why that would make a difference, though.

 Blog Entries: 1 Recognitions: Gold Member I don't see a message either. The entire system freezes up for me such that I can't move my mouse and other displays freeze. For example, I have Zone Alarm which normally shows a display like an audio equilizer when it's processing web pages. Even that display freezes. I still don't know if this only happens when I visit PF because it hasn't happened to me since I've posted about it.

It's right in the middle of the screen, and it's for a split second - literally you could blink and miss it. All I can catch is this guy:

But a lot smaller!

Nope...you are not imagining it. This was reported way back when the new latex system was being tested: http://physicsforums.com/showpost.ph...&postcount=150

Nothing was done about it and I still continue to have the same problem everyday...so I got used to it

 Admin Problem is this happens rarely, on rare configurations (it is not just a OS/browser combination, as other people using Chrome on Vista/Seven have seen no problems), and with a code we don't manage. All we can do is to forward the error reports to MathJax developers. My guess is that they have no idea what is happening for the same reasons - it is some rare glitch, very difficult to reproduce without access to the particular computer on which it happens. Such things happen. I have sold tens of thousands copied of my dyslexia programs in the last 15 years. Sometimes people report glitches that are impossible to reproduce even on identical computers with identical OS. In once particular case my programs were working on several computers in school - all computers were bough at the same time, from the same source, in the same configuration. The only computer that the program refused to work on was the computer used by the school dyslexia and speech therapist. After reinstalling OS to no avail we just switched computers when nobody was looking
 Recognitions: Gold Member I've seen this several times, using Chrome, and I'm fairly sure it is something to do with loading web fonts when I haven't visited any pages with LaTeX on for some time. The machine just locks out completely (not even responding to mouse movements) for up to two minutes, but then it seems to be fine. When it first happened, I thought the system had crashed, but I'm getting used to it.

I have sent the devs this thread to look at. I also see MathJax 2.1 beta is out and it appears to address a ton of issues.

 Blog Entries: 1 Recognitions: Gold Member I didn't have this freeze for a while but it's occurred over the last several days whenever I went to the Random Thoughts thread. jhae2.718 has LaTeX in his signature and had a few posts there recently.
