--- Comment #1 from Todd Chester ToddAndMargo@zoho.com --- Figured out what type of fields this is happening to:
Data Entry type = Field Box
Interesting "Field box & list" works correctly. I changed one notorious box to "Field box & list" and it correct the problem. Changing it back brought back the problem. (You only want list boxes in certain situations.)
If you wish, I can throw you guys together a simple demonstration database (I know you guys do not like unknown stuff uploaded for security reasons).
