Alt-tab from fullscreen

[Coldfire]

DO you know about programming in Dx9? have you ever tried to port a games engine to a later version of Dx? if the answer is no to any of these, then you cant say its simple because you just dont know, there is no allow alt-tab fullscreen=true command in the programming to just change.

There's a step-by-step manual on M$ homepage how to port software written in cpp from DX9 to DX10/11 :P
