Color page trackpad move gets stuck as zoom

I have a Magic Trackpad that I can use two fingers to drag the image around in the viewer and pinch to zoom. In Color, it sometimes gets stuck where two finger drag only zooms. Once this happens, a crash often follows if I don't quit out to reset things.

FCP user trying out DR 20 here!

I see this is a very old post, but I'm experiencing this (Macbook Pro).

I don't think it's related to a specific page. It always happens after usin DR a little while, and it affects all viewers; Two finger move on the Macbook trackpad no longer moves the image around. Instead it will behave like pinch, and zoom in/out. To move the image I have to hold Cmd for vertical, and Cmd+Shift for horizontal. The only way out is to close and restart DR.

I can only guess it's a bug...Or is there a setting somewhere that might remedy this behaviour?
