My OpenSUSE 10.2 system has an odd quirk. To access the menu's in my KDE
applications I need to hold SHIFT-ALT-key, instead of the usual ALT-key.

For example, in KNode, to get to the File menu I have to hold down both
SHIFT and ALT and THEN press the F key.

If it matters, I'm running KDE v3.5.7 release 56.1.

Any idea why this is and how I can fix it?
