In many situations, Glyphs will “quit unexpectedly” whenever I close a font file in the program — often when I have multiple font files open. Any fix for this?
That is fixed in the latest cutting edge version already.
Apparently not, my Glyphs is completely up to date.
Did you activate “Show cutting edge versions” in Preferences?
Oh I see, no I didn’t. I thought you were just being cheeky in describing your latest version of the app 
Thanks.
