BUG: System Hang with BROWSE and SET REPROCESS TO 0

• Microsoft FoxPro for Windows, version 2.6

SYMPTOMS

The computer may hang if a BROWSE command is executed with an ON ERROR routine that performs only the RETRY command while SET REPROCESS has been set to 0.

RESOLUTION

In the error handler routine, give the user a chance either to stop the RETRY command or to try to resolve the problem before the RETRY command is executed.

STATUS

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