Fix: XGServerWindow.m, -windowDevice:

[Georg Fleischmann]

Hi,

here is a patch that fixes an occasional problem with displaced drawing of  
(the items of) menus and popup menus. The problem turned up especially if menu  
items were removed.
The patch replaces a hack in the X backend code which doesn't do it too well.
I played around with the problem and finally replaced the hack with a  
usleep(1) - that did it :-)
