Ubuntu 10.04 With Gnome
Every time Ubuntu goes to the screensaver and I unlock it, Firefox won't let me type anything. I can move the mouse and type in other programs... just not in Firefox. If I quit Firefox and reopen it again, I can type in it.
My keyboard connection is PS/2. Sounds buggish?
Update #1 - Hmm... this time around, I just waited for a minute and it appeared to return to normal. I still think it's a bug but at least it's not as bad as I originally thought.
