Notes can't paste text into this panel in mac rhino

I am attempting to ‘store some text’ in Rhino’s Notes panel (latest WIP for Mac (26 March)
i can ‘paste’ some random text into the ‘Notes’ panel, then Command-Save the (.3dm file), then close that file and then quit the Rhino Application (WIP or non-WIP) - then re-open the file with (WIP or non-WIP) and the text I pasted into the Notes panel is gone gone gone?


What am I doing wrong?
