[PATCH] Ghost Shadows

[Till Krech]

Hi,

since yesterday evening the menu shadows remain on top of the screen if "Drop 
Menu Shadows" is enabled. This is rather strange (and ugly ;).
In kdelibs/kdefx/kstyle.cpp where these shadows are handled. I can see that 
the function TransparencyHandler::createShadowWindows is called _twice_ but 
TransparencyHandler::removeShadowWindows is called only once.
The problem is that the QPopupmenu gets two QEvent:Show events.
It seems to be unrelated to the chosen style. Happens with KDE default style 
as well as with keramik.

The atached Patch fixes the problem. Ok to commit ?

regards, Till
