I tried to run Xamarin Studio on full screen mode and it crashed on me.
Steps to reproduce:
1) Open Xamarin Studio.
2) Create a new iOS project.
3) Debug it in the emulator.
4) Close the emulator.
5) Click View -> Full screen.
6) Witness Xamarin Studio crash and burn in fire at the hands of the OSX gods.
Go to fullscreen mode.
Do you have a crash trace and/or the XS log file?

Xamarin Studio fullscreen crash stacktrace
This appears to be a bug in GTK+ passing a null title to [NSWindow setTitle:]
That said, this shouldn't be a problem in the next release, it will have MacOS Lion fullscreen support, which uses a different fullscreening mechanism.
