Ok for some reason, when I right click in Maya I am not getting any marking menus. The program will still respond to the right mouse click because I can still use it to drag manipulators and move the camera, so I know it is not a problem with the mouse.

I have tried everything... disabling all plugins, uninstalling and reinstalling the program, cleaning my scripts and plugins directory, and resetting all defaults yet nothing has worked.

Any tips on how to fix this would be appreciated.
