Game disappears when minimized

Any time I minimize the game or switch windows via alt-tab, the game disappears. It appears to be running in the background (I can still hear the music, etc) but there is no way to make the window re-appear. Any ideas how to fix this?


Edit: This only happens when running the game in full screen mode.

Do you have open32.dll file in your heroes3 directory? If yes - remove it.

That works - sort of. There is a second VCMI window with no graphical preview. I can click on that and get back to the game, but I can’t alt-tab through windows to return to it. I can live with that!


Mine was called opengl32.dll
and yes, deleting it fixed the problem, I can alt+tab back to it and everything, though the graphical preview is gone, yes.
