Faulting application drwtsn32.exe

Hi there,

I have a user who is having problems every morning with her PC. She gets
this message:

"To protect your system, Windows Explorer has to close."
and
"Dr Watson Postmortem debugger has encountered a problem."

I checked the event viewer and I found the following error:



Event Type: Error
Event Source: Application Error
Event Category: (100)
Event ID: 1000
Date: 09/04/2008
Time: 08:43:54
User: N/A

Faulting application drwtsn32.exe, version 5.1.2600.0, faulting module

Can someone advise
