Hi there,
after installing Rhino for Mac (7.23.2228.13002,02022-10-09) scripts run with EditPythonScript
can not be undone. Eg. try this simple script:
import rhinoscriptsyntax as rs
rs.AddPoint([0,0,0])
Then Undo. On Mac, the point object stays and undo seems to run a previous step, on windows however, the point it is removed.
thanks,
c.
