> Because SDL hooks the keyboard input at a low enough level that it receives the keypresses before the window manager does.  <ALT>-<F4> is defined as a menu shortcut for the Close command in the window's system menu, and then the Close command generates a WM_DESTROY message.  But since the window manager never gets the keypress, the shortcut can't be activated.  (Opening the system menu with the mouse and selecting Close works just fine.)

Thanks, this is something I was expecting. But since ALT-TAB and CTRL-ALT-DEL still work one could say that this is a flaw in the Windows operating system / window manager. Easy enough to blame Microsoft for this :-)
