Some Apps That Just Don't Work on Air?

[wordy]

Hello, I'm having some problems running a few apps on my Air. Firstly, Schoolhouse (http://www.loganscollins.com/schoolhouse/) whenever I try to add a new term I get the color wheel and have to force quit.

The second is XCode. Opens fine, but as soon as I try to open an existing project I get the perma-color wheel and have to force quit.

I use to run both of these apps fine on a 10.5.1 MB, so I'm not sure if it's 10.5.2 that's done this, or if it's the Air. Any ideas on what I can try to figure out what's going on?

Thanks in advance!

Did you migrate anything to the Air or just start fresh? I'm not sure about schoolhouse but XCode of course should work with no problems.

Clean install. I have no probs with any other apps. Uninstalled XCode, restarted and did fresh install and ended up with same perma-color wheel when opening existing project.
