Hi, I just wanted to see if anyone else has been having similar problems. We recently upgraded to 10.5.1 and, after a Windows 10 update, we've been seeing lots of erratic behaviour. Constant ActiveX pop ups using the tools, but the weirdest thing is in making selections. If a query is carried out and the results subset into a temporary layer, if you change the symbology, then close and reopen the attribute table, the selection reverts to the full dataset. We've also experienced layers disappearing between data frames.
Has anyone else experienced this? It's hard to know whether it's a bug in the software, or a local issue based on our IT setup and the interactions with Python and the OS.
