Gini, thank you so much for trying it. This bug must be specifically targeted for me:)
I might try and get a 2 button mouse, probably be useful even if it doesnt solve this particular problem

Anyone else?

"I paint that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence."
