So this is a bit weird. I have a drawing tablet, which is pressure sensitive. I've used in Illustrator, and it works perfectly. The problem is, I can't seem to get pressure sensitivity in Photoshop.  When I go into the shape dynamics, I choose controll: pen pressure. A little warning label (a triangle with "!") pops up, but if I click it, nothing happens. I don't understand why the tablet works with Adobe Illustrator but not photoshop...

I've ttried reinstalling and rebooting and all that obvious stuff. Any other ideas? Thanks :D
