Hello, I'm having a wierd to me problem with FC3. It occasionally seems to stop responding for periods of time. I can't click on anything with the mouse, then eventually it starts responding again. Some useful information: -Using KDE -Using nvidia driver It seems to happen when Firefox is open, though I have that open a lot anyway. I get some error messages from X about "BadWindow" and invalid window parameter. However I seem to get these when there is no problem as well.. Anyone else see this? I tried searching but couldn't find much. Regards, -Colin
