I have written a program and installed at a server, with 5 workstations connect to that program and database located at that server.  4 workstations are working fine, BUT there is one workstation keeps encountering this error "1400 - invalid window handle" when trying to open up any screen in that program.

Please help or advise if you have any idea on this kind of situation.

If only one work station gives problem windows update may be the problem
System Error Code: 1400 Invalid window handle
Background: Microsoft recently released a non-critical, optional update for Internet Explorer 6 for Microsoft Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1. This update changes how Internet Explorer handles web pages that use ActiveX controls. As a result, the MathXL Player generates the error shown above.

You may have to uninstall the Update for Windows XP (KB912945)
