Since I installed new Lion last week, the scroll bars of Lightroom 3.4.1 became crazy. They move less than the movement I make with the pen of my wacom or with the track pad or with a mouse. Each time I touch the bar it jumps moving away. I have checked in case the problem were in the drivers of the wacom intros 4, but it is not because it works ok in the rest of applications in my iMac, everywhere else it works properly. Any help? Thank you!
