I just installed and tried if the Red Baron Pack works. And while I did not play them, The original Red Baron seems to work right, but the Red Baron 3D - the mouse gets stucked. You can move it around the Main Menu, but that is all. You can't do anything with it, not even with the keyboard. It's as if the game didn't recognize any control from my laptop.

Can someone please tell me what happened there.

Hello

For me worked turning off "3dfx logo splash screen" in nGlide configurator.
Hope that it will help you too.

Can You show how to do that?
