If you experience an error when working in Business Central and get the message "The page has an error. Refresh (F5) to undo the change, or correct the error", you also get a confirmation message when pressing F5 saying "There are unsaved changes on the page. Do you want to discard these changes?".

This may not seem a problem when testing the system, but when you have to perform hundreds of different tasks every day, every extra mouse click or keyboard action becomes an annoyance. I suggest to remove the F5 confirmation message as I have already made that decision when pressing F5 - or at least make it configurable.
