Is there any way to customize right clicks on the Mac version?

Perhaps this is a n00b mistake, but as many times as I go into UIPROFILE and set my right click commands, none of them ever work.

Is this a bug in the Mac version, or does some other default settings somehow override the UIPROFILE settings?
All I really want is to bind my right click to dynamic pan!

Version V1R1.3 on OSx 10.6.8
