Wacom pen and touch with Imatch 5.5

[muranod]

(Windows 7) My Wacom pen functions work with Imatch, but I'm having a hard time getting some of the touch gestures to function correctly.

The flicks to navigate back and forward don't work in the slideshow, and scrolling though screens of thumbnails is jerky and unresponsive at times.

I've experimented with settings, including the Windows control panel settings, turning them on and off, but still having a hard time getting these two things to work well, or at all. Wondering if anyone has any success / failures / tips for using a Wacom with Imatch.
