Hello,

after a search, and some trying, the patch

http://www.kde.gr.jp/patch/qt-2.2.2-xim-20001125.diff
(fix an XIM creation)
or the 1116 version, it does not matter,

causes the erronic Alt-F2 behaviour. It also causes the problem that all
desktops get the same background after executing a program, no matter
whether you set different backgrounds for different desktops.

The following part is what exactly causes this. I'm not familiar enough
with Qt to understand why, since I don't even know what an XIM is, but it
surely looks a bit drastic to me to comment out a piece of code and place
it somewhere else where the relationship between the functions is not that
obvious.

Bart
