I found what I think is a bug in Photoshop CS6. The Pen tool keeps reverting back to the "Exclude" boolean mode every time you select the Pen tool. In previous versions of Photoshop, the boolean mode stayed at whatever mode it was set at when no paths were selected. You can see a video of the Photoshop CS6 behavior at https://www.youtube.com/watch?v=8RTHPz...
