Sometimes it just decides it didnt get enough coffee and off it goes...I dont have a prefs folder with it...so the only thing I can do is restore the panel layout...then check everything hasnt gone Yankee on me (Imperial) LOL. I havent had any issues like that with 2011...but 2012..well read some of ctbrams posts mate...he has found every bug so far LOL
