At around 01:50 I open up the Activity Monitor (although it can be tricky to read as the Photoshop document refuses to go to the background when the spinning ring appears) At around 01:05 the spinning ring appears and by then I know that I have to force quit. At around 00:40 the brush stops working so I try to change tool by keyboard shortcut and then by clicking the tool palette. I have a couple of layers and when the recording starts I am using a mask to blend two layers.

This is me working on a texture for a 3D model. I've recorded a short video of what happens (13MB): I use a Wacom Intous 4 with latest drivers. No third party plugins installed (haven't had the time yet) and no third party fonts. The OS X Lion installation is brand new, as is the Photoshop installation. This happens almost every time I use the brush. After that the cursor will turn into that black and white spinning ring of dots and my only way to exit Photoshop is to force quit it. When this happens I can't access the gui anymore and all I have for cursor is the shape of the brush. it doesn't paint or erase or whatever it is I'm using it for. In general I can work a few minutes with the brush before I notice that it isn't responding anymore, ie. I upgraded to Photoshop CS6 a couple of days ago (jumped the Creative Cloud offer for existing customers) and ever since I've experienced several "hangs" when using the brush tool. This is my first posting here so I hope I'm doing it right.
