Ah. I had always assumed that icon went to the help docs directly. Thanks. I tried sandbox and it’s working as expected - no lag.
This is a very corporate laptop so I’m going to say there’s definitely some software running on this directory and all the rest that I don’t want there. That said I see that they set up OneDrive to grab the Documents folder that my vault was in. I copied my vault to another directory that I have access to and I’ll see how it goes. It appears to not lag yet. Thanks!
