My combo box is filled from a dataset. It works but something weird is happening. After the user selects a item in the list it shows up at the top of the list covering the actual first item. If they select the top item that looks like the one they were just on it actually brings up the correct record.

So lets say the Dropdown contains these five items. The user selects the 4th item.
ADB / ADD Frequency 1
ADB / ADD Frequency 2
ADB / ADD Frequency 3
ADB / ADD Frequency 4
ADB / ADD Frequency 5

When they click the dropdown the next time. they see
ADB / ADD Frequency 4
ADB / ADD Frequency 2
ADB / ADD Frequency 3
ADB / ADD Frequency 4
ADB / ADD Frequency 5

If they click on the top item in the list, they go to the ADB / ADD Frequency 1 record not ADB / ADD Frequency 4.
