Glyphs Mini - Beachballs and become unworkable

We have be working with a font for over a week and over the last few days it’s only allowing a few edits before it beachballs. After a while I have to force quit. I have tried this on 2 other studio Macs with the same issue.

Try the latest beta please. Go to Glyphs Mini > Preferences > Updates, activate both checkboxes and press the Update button.

Which macOS version are you using?

OS 10.15.2
Glyphs 2.1.3(99)

All up to date. We have found that an export we made 2 days ago imports OK and we are now able to work in the changes over the last few days. I think the original file had become corrupt.

Can you send me the corrupt file?

I can’t attach a file because I’m a new user!

Any other ideas.

Regards

Neal

Can you please send me the .glyphs file to support (at) (this website without www). We will have a look.
