After some seconds of gameplay this happens (attachment). However, the game still remains playable.
Also the menu is very unresponsive on first start-up. Reminds me of an old issue I had with the 2.0 RC.
(I did not install the game however, I extracted the files from the disk1.cab. I don't see a reason for a setup, at least not for such a tiny game.)
