Any ideas why combo boxes that all have their "auto expand" option set to YES are not auto expanding as I type-in text? They were working last week and I have no idea why they're not working now. Strangely, if I type in any of the entries present in the combobox list (text such as "St. Louis City") exactly as it appears in the combobox list, and then press enter, I get an error message telling me the value is invalid. Then, if I use the drop-down list to find and select "St. Louis City", it allows me to enter this value.
