Our Main computer is on a SSD, I'm unsure of the storage capacity, with my only desktop (front office) on the network. The doctor uses Team Viewer on his laptop, also on a SSD. So there are only two machines really using the database. We upgraded to AC 9.3.1 in June or thereabouts. My desktop was upgraded to W-10 in July and since then we have continued to have multiple crashes a day. At least I do on my machine.
I had tech support (Mazen E. - whom is fantastic, BTW) online two weeks ago for an entire day and he had to reinstall AC on my computer due to a corrupted file. I'd hoped that it would correct the constant crashing, but that has not been the case for me.
