If I edit something in Project Info and click Apply, any further edits cannot be committed without closing the dialog and opening it again as the Apply button is disabled.
I am on 188.8.131.521 on Mojave.
I’ve reported this one previously. The problem is that generally the issue goes away when you save and reopen the project, which makes it quite difficult for the developers to nail down. If you have a project that reliably produces the problem, even after saving and reopening, please post it so the development team can take a look.
As a workaround, you can re-select the project entry in the left-hand list after you click Apply, though of course that shouldn’t be necessary. I’ve fixed this ahead of the next update.
