I've done following:
Copied my entire Gabriel Knight (German CD Version) to my HDD, added the game and selected Windows Version (Could choose between win / dos, is there any difference?).
Intro ran fine, then the two guys were talking. I used the menu on the top, selected restart game, pressed escape button to leave. -> game crashed.
It's reproducable.
Edit: This also happens when i choose DOS Version.
