3 or 4 times now this past week Glyphs has got stuck with a spinny beachball (I had to Force Quit) just after removing glyphs with Command-BackSpace. I apologise for the vagueness of the report, but that’s what it is.
Sometimes it is immediately upon deleting them, sometimes it is with the next action (twice that action was Command-F to insert a glyph in edit view). Sometimes they are fresh glyphs that i accidentally created with Command-D, other times glyphs that have been created many saves ago.
I’m on Glyphs 3.1.2
