Painter 12.

I add a brush folder from a previous collection. I put it in my user brushes folder under the workspace (not in program files (win 7). It works when I first open Painter.
When I exit, Painter auto-adds a new category folder, and the next time I start Painter it complains that the category is not complete (or something) and won't let me load the brush library that just worked.

I have to manually delete the bogus category and then it works, until the next time.

Why??

I love the brushes in Painter but my god this is a frustrating app to work with!
