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!
