Problems with zoom with the Wacom Bamboo Tablet

I have re-installed the Wacom Bamboo software several times, however the Bamboo tablet works in every other way with Rhino for Mac apart from when I zoom. The zoom is uncontrollable. It is too fast. Is there anything I can do to stop this? Thanks

I use a Wacom tablet, maybe I can help, but I need more information. How you use the zoom?

Thank you Zsimon! I zoom with my tablet by swiping the pen either right to left to zoom in or left to right to zoom out. Does this help?

There are countless ways to use the buttons of the pen and Wacom Tablet.
I have never used the pen to do the Zoom (apart from the zoom control window). If I please describe what settings you are using (or better yet a screenshot of the settings) I can try.
