Any comment from Introversion?

Find it hard to believe that no one else has this problem...

Used to be able to play just fine. Got a new Logitech mouse, don't know if that has anything to do with it...

Happens with both Multiwinia and Darwinia. Got the steam versions of both.

Camera goes nuts for no reason. Keeps swinging up to the sky every few seconds, changing position randomly. Makes the games unpossible to play.

Any ideas?
