CAUSE

This problem occurs when Internet Explorer or another program that uses DDE unregisters a DDE server. Internet Explorer or another program that uses DDE then sends a DDE registration broadcast message by using the SendMessage function. If another program that is running on the Windows 2000-based or on the Windows XP-based computer does not correctly process an Windows message loop, the program that uses DDE stops responding.
