I have one user out of over a hundred that freezes SolidWorks more times than not when doing a save-as in SolidWorks. After so many times he started killing processes in the Task manager.  He found that if he kills Internet explore SolidWorks then continues the save as. He also has froze clicking on a PDM folder in explorer and sure enough if he goes to Task Manager and kills Internet Explorer the folder opens.

This is not new to 2016 and it is not his windows profile because his computer has been replaced multiple times of the years.

We are thinking about exporting his IE option settings and comparing them to another users using Beyond Compare to see if anything stands out.

Any other ideas as to where I could start?
