When running _Save, the operation blocks all running instances of Rhino WIP8, not just the one where _Save is running. This is annoying, since saving a file can easily take serveral minutes with large models. This didn’t used to be the case in R7.
I’m now on (8.0.23241.14305, 2023-08-29) and can’t repeat the issue either. I tried with several large models, but it all seems fine. Not sure why Rhino locked up when I reported this a couple of weeks ago
