[kubuntu] Mouse Clicks Stop Registering

view story

http://ubuntuforums.org – Hello, I'm having a problem where soon after booting, my mouse clicks stop registering. I can still do everything using the keyboard, and I can still move the mouse, just can't click. Sometimes, though, I can click in certain places; in a window I already had open, or only on a panel, for example. I've tried changing the mouse out and the problem still occurs. I can fix it by logging out (at which point I get a crash report from kmix) and back in, but it will just happen again within a few minutes. I've also tried disabling desktop effects, as well as closing all widgets, but that didn't solve (Hardware)
