Minimaze Window Issue

[Ermac]

Here is my issue:
1. In Software renderer I can minimaze the fullscreen game by taping the windows key, read for instance something from IRC and go back to the game;

2. In Open GL i can't minimaze the fullscreen game by any way and that attempt ends up with some lag or game being choked completely (With or without use Open GL compatibility options).

I talked about this issue with Qent and he told me he was able to do that.
Next, I can minimaze counter-strike in Open GL with windows key but I can't Zandronum (Skulltag) and I can't understand why so.

Instead when I hit windows key in Open GL my toolbar is visible, other part of the screen became black, other windows such as messenger or google chrome gain ingame gamma. Why it doesn't simple minimaze the window as it does for me in software renderer. That's the problem.
