Hi, I'm on PM 6.0 b4155, on an iMac 27" 5K running 10.14.6.
Scenario: importing images, I click Destination folder and in the dialog that opens I select my template destination folder (which contains numerous folders I'll need now and later) and duplicate it. I can then import to that new set of folders. But if after duplicating the folder I then rename the new set of folders, after selecting the destination I want to import to and returning to the regular import dialog I can't do anything. Every click, on any part of the PM interface, results in an error beep. No window has popped up that I can see that requires prior attention, even though it's acting as if something like that has happened.
