I was thinking it would me a hardware thing rather than software. The only project of mine it did it on was Melvin which has a lot of controls and a lot of scripts so wouldn't be much help in pin pointing anything. But hopefully others who have suffered/are suffering with this can help you out with some project files.
My reply was mainly as a bit of advise for anyone who does suffer an unresponsive GUI so that they can at least save their work.
DJ, here's the file. I had to rebuild some of it because, well, lost some changes from the hang. But it's pretty much the same thing. Don't know if you'll learn much, but let me (us) know : )
Cheers!
