As noted above Autocad 2015 LT for Mac is freezing when I open a file on my desktop.

Operating system OS X 10.10.2

Processor 2.3 GHz Intel Core i5

16 gb memory

Autocad Product version J.51.M.313

This a new occurrence.

I have reset Autocad, checked system permissions and repaired.

Every time I selecct File - open and then desktop the Autocad freezes, and I have to force quit.  Everytime.

If I go to recent drawings, this does not happen.
