Thanks man! I'm all into opensource freeware these days, so the bulk of the work is done in MyPaint and then there are some tweaks done in GIMP.
My Paint is an interesting program, very responsive to the tablet I'm using, but lacks a lot of functionality you get in other graphic editors. GIMP is able to supplement most of that for me, but for whatever reason will not play nice with the pressure inputs from my tabPC.
Between the two I'm able to do most of what I want, but it can drive me a little nuts.
