After Yosemite upgrade, two finger pan only zooms,even after preference is checked

Hi, I am running the latest build of Rhino for Mac and I just updated my Macbook Pro to Yosemite. After the upgrade Rhino is essentially unusable because using two fingers zooms and does not pan (like it did before the upgrade to Yosemite). I have checked the box “use two fingers to pan” under Rhino->Preferences->Trackpad but still the program will not pan. How can I fix this?!

This will be fixed in the upcoming WIP. Sorry about the current wonky behavior.
