using the full screen function will crash TPT and if i used terminal to launch the app(Powder.app/Contents/MacOS/powder-x) this will show up:: CGDisplayBaseAddress is obsolete and returning NULL for display 0x4273000 so i guess this is the only problem using TPT in 10.7
Fullscreen crash looks like a problem with SDL, rather than a problem in the Powder Toy code. I don't think there's much we can do about it. http://bugzilla.libsdl.org/show_bug.cgi?id=1215
