Comment 2 for bug 468223

I'm having the same problem. I've noticed it mainly in Firefox where it's extremely annoying. I also noticed it picking stuff along the Gnome toolbar across the top of the screen, but that seems to have gone away.

The problem has no effect on my keyboard, unlike the original bug reporter. But what I see is, attempting to click on a link in Firefox causes the cursor to change to an up arrow. Then when I move the mouse it drags the link. So I guess it's just like if I had held the mouse button down. But of course that's not what I did. I'm now also seeing another manifestation which is, I clicked on the scroll bar to scroll up, and now the mouse keeps scrolling the screen even though the mouse button is not down.

I think it's a bug because this same computer worked exceptionally well with Ubuntu 9.04 and the only change to the system was the distribution upgrade to 9.10 on Friday (i.e. release version).

The computer I am using is a Dell Latitude D600. If more information is needed I'd be happy to provide.

I'm going to try re-booting (I'm pretty sure I've tried this before but I'll do it again to be sure) and I'll also connect a USB mouse to test that. I'll post the results.
