Hope someone can help me with this --
I can't transform items or selections anymore, other than by typing numerical values (for example 90%, or -5 degrees).
My problem is that I can't click on the little boxes at the corners of the square that appears when you want to transform or scale something. As soon as I try they disappear, and I have to transform via numbers (quite a pain until you get it right), and distortion is impossible tis way. The problem appeared shortly after installing Painter 10. I run it on a Macbook Pro connected to a Wacom Cintiq. Drivers for those are all up to date.
