Hi, I've been using OpenSim 4.4 to edit muscle paths, which was going fine but now suddenly in all models when I select (in GeometryPath) and move a point in the GUI, it immediately deselects it after moving, which it was not doing before (selection of path points persisted). I've reinstalled + rebooted; same problem still.

Thanks for reporting. I'm also seeing this in the OpenSim 4.4 GUI. Specifically, this seems to be occurring for me for muscles with wrapping but not for muscles with no wrap objects. Is this consistent with what you're seeing too?

Ahh, interesting, yes that is the case for me too; wrapping is the root cause, it appears.

And same problem w/wrapping now in 4.3, oddly enough, although it seems much more tolerant of allowing you to re-select muscle points in the visualizer window after they get deselected (4.4 always seems to want to select surrounding bodies not muscle pts, in my experience lately).

Thanks for checking that and helping us isolate the issue, it's super helpful for debugging on our end.

One workaround that is working for me is that after moving the muscle point (and then the GUI deselects it), I can at least get back to it by checking a different path point, and then checking the box of the original path point that I want to work with. Definitely not ideal but hopefully can save a little time.
