Platform-specific bugs encountered:

Runs very slowly and jerky. Backgrounds flash in and out, and are sometimes invisible. Mouse cursor sometimes doesn't move, and does not change back to arrow when I move out of the PS window -- it becomes invisible until I am over the Dock.

I just discovered this game 2 days ago, and want to play it. I'm on a search of the forums to see what I can do to make PS work better on my laptop.
