Hello, is there anyway to play in windowed mode, on a wider screen. In this state, as full screen, the game is not worth playing. Hope somebody can help?

You're not giving us nearly enough information to go on. Which version of the game are you trying to use and what OS are you using? Are you running it directly under Windows, using wine (with Linux) or DOSBox? We may need more info, but that should be enough to start with.

Hey, can I join the discussion here? I think I will have the same question, so I don't wanna start a new topic.
Game opens fullscreen, which makes it uneasy to look at.

For me it's Heroes 3 Complete, playing on Windows 7 (also I use separate 24 inch monitor).
I've read about pressing F4, but that didn't work (wants me to change resolution on my pc).

Use the HD mod.

Took a while to find it. Thanks though.
