yes, it's corel painter 4. I haven't upgraded to 7 (expenses!), but I've heard it's as buggy and unpredictable as the other painter versions.. Yep, anti alias is checked and I've tried most other things too with no luck. No matter the width or size of the painter tool, nothing gives smooth correct lines with my tablet (I'm talkiing freehand, not vector of course, so it's not the paths, layers, vectors or any of that, it's just the freehand drawing that seems to be very jittery and unprecise in Adobe 7. Yes, I haven't used the mouse for years either..It's just so annoying going back to less when you can have the cake :)
