None of the radial strip functions of my Cintiq 21UX work after upgrading to latest Illustrator CC 2014 in Mac OS Yosemite.

I can select the different functions for the strip, like zoom and brush size but using the strip doesn't do anything.  It worked in the previous versions of both Illustrator and the Mac OS.  All of these functions work fine in Photoshop CC 2014 however.

Any help would be appreciated, Sam.
