In creating cues, I’ve noticed that Edit > Undo/Redo isn’t working for me. Instead, it is applying to the last applicable action. I’ve got that behavior ingrained and this is admittedly a hard habit to break where it seems like it should work. Is this a feature or a bug?
You’re finding that after you create a cue, you can’t undo its creation with Ctrl+Z/Command-Z? In general this is absolutely possible. If you have a reproducible case where you find that it consistently prevents you from undoing the creation of a cue, please attach a project here together with the steps required to reproduce the problem. Thanks!

Yep. Also with Option-clicking (which is how I mostly do it). In predictable fashion, as soon as I restarted everything, it was working again. 
I’ll certainly be on the lookout if it happens again. Thx for your time!
