[GD-Windows] Alt+Tab in fullscreen with no other apps running

[Oscar C. <oc...@fr...>]

Hi,

Does anyone know if there's something I have to do (or avoid doing) to make 
my game minimise when the player hits Alt+Tab whilst running in fullscreen 
with no other apps running?

My game isn't minimising in pre-Vista versions of Windows, but other games 
seem to do so. Windows isn't sending me any WM_ACTIVATE or WM_ACTIVATEAPP 
messages. I am getting WM_NCACTIVATE and WM_CANCELMODE, and I'm passing 
these on to the default WndProc expecting it to handle any necessary 
plumbing.

With other apps running the Alt+Tab behaviour is correct in fullscreen, but 
in this case Windows is sending me a completely different sequence of 
messages.

Thanks in advance,
