May gut feeling is that a recent update to SUSE 11.2 (openSUSE 11.2 (x86_64)) is the culprit (I've started a thread there too), but whenever I hit a break point my desktop freezes. The mouse moves but no clicks and no keystrokes are recognized. This first happened in 8.1.3 which prompted my to move up to 9.0 (IU 93.13). I see nothing untoward in any of the system logs. Ctrl-Alt-F1 is required to get out of gnome and from the command line I can kill either IntelliJ or the debugged application which leave the other (app or idea) perfectly happy.
I've turned off compiz and that hasn't helped.
The app in question is started via an eclipse plug-in (3.0.1).
Any clues appreciated.
