Just tried  a new blank file, then  Draw > Notes > Comment, Placed the default Note on drawing.

Then File > Save   and immediate crash out exit from file. !!

Restart 5-2  - Yes to Offer to recover  - blank file.  Also tried a few tracks - no problem.

Then again Draw > Notes > Commen, Placed the default Note on drawing. Immediate crash on Saveing.

So does seem to be a prblem with the "Comments"
