I just spent most of my morning trying to solve what appeared to be problems with mates in an assembly and file associations of drawings.
Then I had someone open the same assemblies and drawings and when they opened them there were no problems. After restarting SW and opening the same assembly that looked messed up before, it then opened and looked correct. I am running a "Repair SW" routine as I am typing this in the hope that I won't have this happen again. We are all running SW17 SP4.1. Anyone else ever experience anything like this?
