Hallo !
I can't give you a line of code, but I know, it is *not*
kpanel (or kde) specific.
I can reproduce same behavior under fvwm2 (i.e. *without*
KDE) and Netscape or knews. It looks like some app creates
an undecorated (modal ?) window, lost track of it and is
somehow blocking the windowmanager.
I think it is the windowmanager, because (under fvwm2) a
restart of the windowmanager (via keyboard, mouse moves around,
but doesn't do anything) *or* killing the app brings things
back to live.
*Note* : I have *never* seen this on modern, fast maschines.
Only on my good old 486 @ 66 , 32 MB RAM, slow VLB-gfx-card.
May be a racecondition somewhere.
I can give detailed reproduction-instruction (works ~25%).
