Navigation tools freeze the system without effecting the CPU useage.

I have changed the RAM preferences to 100%, 25%, and 10% with no change.

I am guessing that it may have something to do with MM and NVIDIA?

I have upgaded and installed MM 2014 from service pack 4 and have the latest NVIDIA driver.

I installed MM 2013, same result.
