I've had a fullsize for a couple months now and I've had it randomly freeze up completely about 4 times. It seems to happen completely random. The most recent time I grabbed 6 fixture and was just swiping over the color picker and the console just locked.
My only fix is a hard reboot, and this is less than ideal. Unsure if this is a software or hardware issue.
I am running on the most recent (1.6.5)
