Mic, I double checked that menu: have always just displayed Date, Time, Description, Notes Flag, and Categories. I've gone thru my Reminders, and all my self-made To Do's and confirmed "Date Completed" isn't in any of them. So yes, not displaying it is correct, and is how I've got my fields displayed now. But no, it doesn't have any affect on the Date Completed field. Where it bothers me is when I hover over an event and see the 'incorrect', but logically correct Date Completed. On repeating, say a monthly event, those that have been marked "Completed" show the most current completion date. Those that are still outstanding show no Completion Date.
I think that this is something that I'll have to live with: since RF DOES LOGICALLY use the date that I mark an event as "Completed".
So on my wishlist to the 2 guys that wrote this terrific program, is the ability to edit/change the "Date Completed" field.
I'm gonna try and close this topic, since I don't think a resolution exists. But I sincerely thank you Mic for trying to help me - Thumbs Up!! Regards, Deb & Dakota
