DDE problems on Windows XP

Has anybody come across issues where applications that use DDE simply stops responding.
An example would be Excel trying to pull market data from Reuters or Bloomberg.

Often a rogue process running in the background (usually dwhwzrd.exe) needs to be killed to get Excel working again.

Its not always dwhwzrd that is the culprit and sometimes it is another process locking up the DDE. Sometimes the only known cure is a reboot.

Any pointers to a cause and long-term fix to avoid the problem will be gratefully received.
