Allow user to switch to and from full screen

i noticed I can't uncheck this anymore... is this right?

It is checked and yet the user cannot switch using ALT-ENTER or by means of the menu. This is true even if Change Resolution Mode is checked or not... earlier versions of this game did allow it and it worked well.

nevermind... this is because I switched to DirectX display mode.

fullscreen isn't in DX yet, which is why
