Thank you for your responses. Maybe I need to upgrade for tiger to Leopard - I dont seem to have other problems with OS so I'm a bit reluctant to do it:) I thought it might be because I use a track-pad not a mouse, but e-on claims they tried with both and didnt have a problem.

"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."
Man Ray, modernist painter
