There is quite a bit unpredictable in SDL-Win32. I tried to get ekiga 
fullscreen running on Windows this weekend. The outcome is not very 
satisfying. I made the observation that ekiga does not crash but happily 
continues behind the SDL window when you switch back from fullscreen. 
But don't dare to switch to fullscreen back again. The fullscreen window 
can be removed by pressing the disconnect button. So SDL for Windows 
just did not remove the window.

The rest of the day I spent convincing SDL to do so. In principle
1) SDL-Win32 does not like keys to trigger its quit.
2) Any events or other stuff which happens to SDL-Win32 between polling 
and SDL_QUIT make the window stay there.
3) As documented SDL_WM_ToggleFullScreen does not work on Windows
So I used the right mouse button for returning, grabbed input and quit 
SDL as soon as I get notice.

Attached is a patch that makes win32 fullscreen work for me. Not very 
nice but perhaps a start.
Regards
Michael

P.S.: I will be off for two weeks.
