The information in this article applies to:

- Microsoft FoxPro for Windows versions 2.5, 2.5a, 2.5b, 2.6, 2.6a

SYMPTOMS

When a List popup is defined with the PROMPT FIELD option in the Screen Builder, and the field displayed in the list box is the key field for that database and contains duplicate records, the navigation buttons no longer function when a duplicate field is reached.

RESOLUTION

To resolve the problem of the navigation buttons hanging in the list popup, you must ensure that the record values in the field referenced in the list are unique for each record in the file.

STATUS

Microsoft has confirmed this to be a problem in FoxPro versions 2.5 and 2.6 for Windows. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
