BUG: Empty List Box Locks Up FoxPro for MS-DOS

ID: Q109155

The information in this article applies to:

SYMPTOMS

When the PAGE UP key is pressed in a list box that gets its information from a field in a empty database, FoxPro will hang (lock up) the computer. FoxPro will hang if the PAGE UP key is pressed twice, or if the PAGE DOWN and PAGE UP keys are pressed one after the other.

STATUS

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