Did you actually review it a little bit? I wrote that in 5 minutes, did
a few tests, saw it working and sent it to you for some sort of "hint"
to what's going wrong there...

Hm. I think for 6.9/7.0 we should be keeping it, perhaps (IMHO)
declaring it deprecated. Still a lot of DGA apps around (not even
mentioning vmware in fullscreen mode - pretty useful actually), and we
should give the app developers a longer timeframe to kill it than until
6.9/7.0 is out. Question remains: What is going to replace it (if a
replacement is needed, what I can't judge)
