Is it just me or none of the flipping WE are able to minimize my Open Arena or Alien Arena window for me to take a peak at my desktop, e.g. ALT + TAB on Winblows? I tried metacity/xfwm4/kwin and all of them have shortcuts for window minimization e.g. ALT + F10 but when pressed the 3D apps ask me if I want to exit out of the game or they don't do anything at all.

This flipping sucks.
