PS CS5 quickie.

So I just got my computer updated here at work w/CS5 and it is incredible! Here's a first quickie. Really dig the color mixer! But i did notice the pressure gets a little jumpy as you see some of the lines are insanely thick (which i did not press down that much) then goes right back to its correct pressure spot. anyone else expeiencing this on their Intuos? Anyway, there you go!
