This is a game issue. Alt-Tab doesn't work for me in some old games either.

Yes, I'm on Win 10. Good to know. Thanks!

Yes, it seems to be a error with .IT music file / bass.dll. After I replaced the bass.dll it works fine but (as ZellSF said) no sound. Well, you can't had them all. Thanks for the info!

That site is fine, I downloaded many demo games from there. Of course I copied everything to the game directory. But I had the game unpacked and started it from drive D: \. After you confirmed that it works I installed it in C: \ Program Files (x86) and it really works without problems. Thanks a lot …
