Right click force close

Everytime I right click(either two finger click or trackpad rght click or mouse right click) in a max window, max hangs and I have to force close it, this happens weather I am on a object or not on an object. This happend also when I click on Explorer Settings at the bottom of the Max Patch window.

My computer is a MacbookPro 13" mid2012, running 10.8.2 and the problem occured with the MaxMSP version 6.0.8 and 6.1
