Trying to get Eagle Eye Mysteries to run on DOSBox for by nieces & nephew, but I'm running into a bit of an issue, and I think it might be DOSBox related.

It works just fine in windowed mode, but the moment I have it start in fullscreen, it triggers a weird issue:
Should you use the mouse to skip intros, the mouse will then stop having any effect on the game whatsoever. Going to windowed mode fixes this.
This issue does not occur if you use the enter button to skip the intros.

Unfortunately, I don't have a real DOS machine to check whether this is a problem native to the game code, but the fact that it works fine in windowed mode makes me think it's not that.
