Try xprop - this will envoke cursor, click on the window that you can't close, this will show you in the terminal the pid , something like: _NET_WM_PID(CARDINAL) = 13344. Then - "xprop | grep -i pid" - this will show you the process too. Then something like "ps -ef | grep pid" <div>On 6/26/07, Mike McCarty <<a href="mailto:Mike.McCarty@sbcglobal.net" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">Mike.McCarty@sbcglobal.net </a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> 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.
