Scroll browse widgets are accessible but Navigational buttons and fill-ins can not be used.

DDE get/send calls are used to communicate with a Visual Basic application.

The lock occurs when a Program attempts to run a procedure within another program.

The procedure is not being executed.

Code has been modified to save a handles unique id.

Microsoft updates have been applied to machine.

CHANGE:

Client machines Operating Systems were changed from win95 to win2k professional.

CAUSE:

Messages built around DDE calls shows they are not completing.

Storing values within Progress instead of Visual Basic lessened the occurrence of the problem.
