Geneforge 2 exposé and lag

[MrHell]

Hey, I've recently decided that I would play through all the Geneforge games in order. Having just finished G1, I've downloaded the G2 demo.

 

When I move the cursor into the corners of the screen it brings up my various exposé windows, is there a way to stop this from happening? It never did it with G1- and I'd rather not have to disable my exposé

preferences every time I want to play.

 

Also, the cursor and graphics seem slightly, joltier... it could be my imagination, but I'm pretty sure that it is not running nearly as smoothly as Geneforge 1 did.

 

Is there a way to fix any of that? Or should I wait for the Intel versions?

 

Any help would be greatly appreciated, I had a blast with G1 and I'm looking forward to buying G2!

MacBook Pro 2.33 GHz Intel Core Duo

OSX 10.5.5

Geneforge 2 v1.1

 

EDIT

 

I've found that the earlier version of Geneforge 2 doesn't have this problem, and works fine. I can't find earlier versions of 3-5 though.
