> Now, I'm all for blaming Microsoft for their multitude of screwups, but this is really just a design issue, and it's perfectly consistent behavior.  <ALT>-<F4> is supposed to be handled by the application, but <ALT>-<TAB> and <CTRL>-<ALT>-<DEL> are system-level commands that get handled by the OS.  If you press those keystrokes, SDL will probably generate the appropriate keypress event, but since the handler's registered at the OS level and not the application level, you don't see any blocking behavior.  <ALT>-<F4>, on the other hand, is a menu shortcut that has to be handled by the application.

Thanks again, I think today I'm learning quiete a lot. I always thought ALT-F4 was handled by the window manager, but apparently this is not true for windows, maybe for KDE. So maybe it would be a solution to remove the ALT-F4 shortcut from the menu entry, because I think nobody will argue that it's a bug in every SDL program when the menu says <close ALT-F4> but ALT-F4 is not working.
