I use GNOME with FC2 and have encountered an odd circumstance. I was running K3b to burn some images, and it popped up some windows. When I shut it down, I killed the main window, and one remained. It is a small window, and is blank (normal background color for those windows). I can use the little buttons on the frame the [-] [o] [x] just fine, except that it won't go away. When I use the [-] box it does go on the task bar. But when I use the [x] box, eventually the "Window is not responding, [Cancel] or [Force Quit]" comes up. Selecting Force Quit does not make the window go away. I cannot find any process associated with that window using ps. I'm sure a reboot will fix this, but I'd like to have some idea what is going on.
Thanks for your time.
Mike
