Thanks so much for the help. I was in the middle of trying your macro & did something else that worked!
I'm posting what worked for me in case anyone else gets in this terrible situation:
Go to Security & Privacy & turn off the engines access in Accessibility - you can then launch KM - make sure you deny any requests for access to anything by KM - then kill your macro.
I had gone into Privacy before but only disabled folders, not Accessibility.
Anyway, thanks again!
