Vista Scrolling Mess: Find a Solution Here!

[swty todd]

i face this weird problem while scrolling in Vista.
It happens like this: suppose I am scrolling using the vertical scroll bar and clicking on the downward arrow on the scrollbar.Now just after releasing the button if i point my cursor on the screen , the screen moves down.But this doesn't happen always.I mean ,it seems to work perfectly fine one second and the other moment i feel like the scrolling is out of my control.My XP has no scrolling problems though.
Can you suggest a solution?

Are you by any chance using a laptop with a touchpad? If that's the case, then you can double tap on the center of the screen to escape this 'scroll lock' mode.
