What version are you using? I have been running into a few folks who are having some bugs with 19.2 I am still running 18.3 flawlessly so far. We have a fellow user here who has a 19.2 install freezing up at right about an hour of use like clockwork. Trying to chase that down.
I have one machine on 18.3. I tried to move to 19.0 early but my video card was not supported. Just been lazy since and have not tried to upgrade. My other machine is 19.1. Both work flawlessly
