Undo stops working (mostly)

Now I’m not sure exactly what causes this to occur but it’s been happening for the last few builds.

Currently running the next to last update to Mac OS on a M2 Mac Studio.

Occasionally undo stops working. Doesn’t matter if you invoke it from the keyboard command or the menu, but the menu highlight fires when you select it and nothing happens.

If you manually go to the menu and bring up the multiple undo pane, that works but the menu and KB command flavor does not.

Quitting Rhino and restarting will bring it back but once it occurs that’s the only resort to getting it to work again.

Anybody else run into this?

Hi @LewnWorx pls run _SystemInfo and post back the results.
When undo stops working what do you see in the command line? (I assume “nothing to undo”)

If this happens again, pls run both _AuditUndo, and _TestCurrentUndo, and post back the results.
thanks!
