In Find mode, I type a date into a date time field and get the following error message:
Invalid input '08/12/2002', didn't comply to the format 'MM/DD/YYYY'
On another table, I enter a range 08/12/2002...08/18/2002 and it finds all records.
On another table, a date field will not accept a change.
If this has happened to you, check the format properties. I had set them, inadvertently, to DD-MM-YYYY instead of DD/MM/YYYY and was entering dates as DD/MM/YYYY
