SOLVED - Xojo doesn't delete unfound projects from Recent Projects menu

Am I missing something. Xojo 2015.4.0 doesn’t seem to delete missing Projects even after saying I want to remove the reference from the Recent Projects Menu.

I have tried saying Remove them, and then both doing a Save and a Save As, but two pesky entries remain. I am running on Windows 10.

Had one last try after posting, and found the answer - I pressed the OK button without opening any of my other Projects, it worked.
