Suddenly, like within the past week, Solidworks 2016 has started hanging every time I finish adding an assembly constraint. This is not a large assembly and they aren't complex parts. I've had this version installed for several months and it didn't do it before (or I'd have gone crazy by now). I turned off auto-save. Didn't make a difference. I found that SW was using the integrated video card on my laptop, so I ran it with the "High-performance NVidia processor," didn't help.
It's like it just checks out after every assembly constraint function for 5 to 15 seconds. Anyone have any ideas as to why or how to make it stop, other than giving my computer to IT for re-imaging?
