I've had the most interesting problem since I installed KDE over Ubuntu Feisty Fawn....sometimes (apparently randomly as far as I can see), when I attempt to start a program, I will get the flashing cursor to indicate that the program is attempting to start, but then the cursor returns to normal and the program does not start.
Once that happens, I am not able to start the process manager either to find out if the program is already resident. The only way to restore normal behavior is to restart X. I have observes this behaviour with Firefox, Gimp, Amarok, Rhythmbox, and a few other programs, so it does not appear to be program specific.
Can anyone suggest a cause/fix for this problem?
Thanks.
