Rhino for Mac Zoom does not work

I just downloaded the latest release Wenatchee 2013-12-23: the zoom function does not work anymore. Neither the magic mouse (scrolling the middle part of the mouse), nor the magic trackpad. I can use only the key combinations or the command icons.

I just downloaded the new version.
Command+2-finger swipe on the track pad Zooms just fine here.
This is how my Preferences - Trackpad options are set.
I don’t have a Magic Mouse on my little MacBook here at home.

Thanks , I resolved. It was a MAC problem. After a restart, everything worked well.
