Glyphs 4.1.1, I am constantly seeing this:
I haven’t found any kind of observable logic to why or when this pops up, but it feels like every other time I am wanting to undo something it is not working… which is annoying for an undo feature, to say the least.
Can I somehow debug this?
Could you send us the app diagnostics (Help menu → Copy Diagnostics) and paste that here or in a private message (click my profile picture → Message)?
This can often be caused by a plug-in that messes with some internals. The diagnostics contain which plug-ins are installed and which software versions, so that helps a bit reproduce the issue. And if you can remember the last few actions before the undo problem appeared, that can be helpful to trace the issue to its source.
And could you try the latest cutting edge version. It has some undo related fixes.
