[Hampshire] Losing button events...

Hi All.

I've installed Fedora 13 on an old Dell Latitude laptop. I'm having some
trouble with it.

Frequently, when I click the left mouse(pad) button, the button I'm
pressing doesn't work - it changes colour to indicate the press, but
doesn't do anything until I move the mouse pointer. Looking at it with
xev, the ButtonPress events are all seen, but the ButtonRelease event is
frequently missing.

Has anyone seen this before?

Thanks!

Vic.
