Uninstalling all games and reinstalling Commandos: Behind Enemy Lines with no effect. Neither does changing the resolution on my desktop settings. Changing the resolution in the game does effect the dimensions of the minaturized screen, but nothing has made it fill back out to the edges of my laptop's natural screeen. What I've noticed is that the my volume control and control panel are also shown in this reduced size window, so whatever is going on, it is doing it to the entire screen and not just the game window. I haven't played any of the Commandos games since, but last night, I tried to play and every one of the 4 games in the collection (including the expansion) are all confined to a very small window in the center of my screen with a lot of black screen all around them.
Please help! I bought the Commandos collection back in March and everything worked okay then except that Commandos 3 was in such a low resolution (which I've heard is a common issue).
