The problem is, as Pisces said, the voice command program trying to activate and bring itself to the foreground, minimizing DW in the process. Sometimes with certain video drivers or cards, the graphics mess up when a game like DW is minimized or moved from the active window.
While I don't get this graphics problem with DW like I do some other games (though the voice command program still tries to hijack my computer
), the fix
should be the same: try and click down on the taskbar where you think the DW icon is to re-maximize it and bring it up front.
Don't try to exit the voice command program because every time you go back to the options menu it will reactivate itself and start the whole problem over. Just let it run in the background, it wont hurt anything, and you can go to the options menu without problems.
If you can open DW in windowed mode and then go to the options, you should see what I'm talking about, and you can switch over to fullscreen once you have the voice command program running in the background.
Hope it helps.
