Hi everyone =)

So i'm using watercolor brush in painter X, then i use the eraser a few times, and decide to undo [*control+z] a eraser stroke.

"Problem" starts: The eraser starts working in a diferent way (it draws a rectangle in the are i've stroked), and if I try a new watercolor stroke over the ones that were already present before the undo, a square clean area gets around the new stroke =(.

I'm not sure if this is suposed to happen or not... but i've found no mention to that on the help guide >_<.

My first post andi'm already bringin a doubt , sorry for that. ^^''

And thanks in advance ^^
