So a little background, I tend not to shut my Mac down and let it sleep. I often have many preview windows, Eclipse, Textmate, iTunes, Skype, Entourage, and Firefox open all the time. About 30 minutes ago, I went to open a Textmate workspace and my system just crashed. Well actually it didn't look like a crash. My iTunes was still playing my song and so far as I can tell everything was great, until I tried to do anything. In essence my screen was completely frozen. No buttons worked, my iController wasn't scrolling the song anymore, the dock didn't response. Nothing worked. I couldn't force quit either. Of course my song was still playing. I've had this happen to me a few times now. Honestly I'm wondering is it something I'm doing? or an application I'm running that is causing this?
