Undo issue

Undo stopped to work

Hi @gabrielefx
Is this the case on all files - even a simple cube - or is it file specific? What happens if you re-start Rhino and try again… same thing? Also run the SystemInfo command in Rhino and post the result here. It could be a plugin messing the undo settings up.

Restarting Rhinoceros no issue, let’s see if it happens again…

I suspect it is RH-78325 Layers panel not ending undo record

This happened when you opened section style and canceled. Let me know if in case it’s anything else at your end.
