Well I do believe in it as I use in PS / LR and all the other programmes just fine and dandy.

The last thing I want to have to do is go to the physical effort of actually pushing down and clicking the trackpad when I can just gentle bounce a finger tip off it.

What I am now saying is that there is a difference behaviour in the way the programme responds to the same action on two different systems.

Works as expected on my Mac Pro but not as expected on my Macbook Pro.
