We received a hydraulic motor in an STP file today. Out of curiosity I stupidly decided to open and inspect it. After the file opened I was asked if I wanted to run Import Diagnostics and I again stupidly selected yes. That was an hour and a half ago. Is there a way (short of closing SW) to stop the diagnostic process so i can go back to work?

I am running the glorious 2016 SP1.
