Version: (using KDE Devel) In a new KDE installation I still get the warning dialogs that, for example, kopete shows when you close it for the first time (see attached image) This means that it can take considerable time before the user actually OKs the dialog and the main kopete window is actually closed after the user clicks on the 'X' button. Due to this normal interaction the reaction of kwin to pup up a request to terminate the closing application is not very user friendly and should be avoided. I guess that the opening of a dialog with as a parent the closing window should stop the timer to popup the kwin warning dialog.
Created attachment 12671 [details] example
I just noted that when I click the close on a konqueror window and get a popup to ask me if I want to close one tab instead of the whole app I can choose to close just the tab. After some time kwin pops up the question to terminate konqueror! Setting priority to very high since this is IMO a bug that can not be present in the released 3.5 version.
(That's what severity is for, not priority.) It of course checks for this case. The dialog really comes up only in cases when the application does not respond. Worksforme. Given your previous bugreport, there's probably something strange with your setup.
It now works correctly. Must have been a flaky cvs-version of x.org...
Please, REOPEN this bug. I am experiencing the same problem on my Gentoo/AMD64 box from a long time now. Confirmed on KDE 3.5.2, 3.5.3 and 3.5.4. Every time I click on the close button and that the application does not close immediately (because of a save|discard confirmation dialog or other). A dialog pops up asking me to terminate the non responding application. I can confirmed this with Kcontrol, try to change something without applying changes and close the application, with Kile, when I try to exit from a 'View' like ViewPDF, ViewDVI,... It appears that some people have the same problem but always only on AMD64! For more info, look at my original bug submission @ Gentoo: http://bugs.gentoo.org/show_bug.cgi?id=130272
Indeed, I can currently perfectly reproduce it like this. Start konq. Create a new tab. Press close button on kwin decoration. On the 'quit or close tab' choose cancal or close tab. Wait 4 seconds And there it is; Window with title "about:blank - Konqueror" is not responding. This window belongs to application konqueror (PID=22917, hostname=localhost). Do you wish to terminate this application? (All unsaved data in this application will be lost.)
Using 3.5 branch rev: Following usecase from previous comment.
