Running Parallels 9 on my Macbook Pro Retina and Windows 7. FL Studio has many rotary knobs that stick fully low or high as soon as I try to move them with either a mouse or trackpad. This appeared to be fixed in Parallels 8 when I turned OFF the SmartMouse option. However, in Parallels 9, the SmartMouse options are different and none of them resolve the issue. I just upgraded to 9 and really don't want to downgrade back to 8. Suggestions?
