Another Dr. Watson question...

(I posted this problem first in the xp.help_and_support forum but got no
relpies. I apologize for repeating it here in this forum, but I really need
some help.)

SYSTEM: Window XP Home - SP2 - with ALL of the updates

I am suddenly getting (several times a week) an error window stating that
Dr. Watson has encountered an error and must close. I usually end up having
to log off and then back on again as the systems seems to hang after I
acknowledge the error.

Through the Control Panel/Admin. Tools/Event viewer, the 'error' description
was that the faulting application was 'drwtsn32.exe' and the faulting module
was 'dbhelp.dll', and something about the 'data base being locked'. I
searched the system drive for that particular .dll and I have five or six
copies (different version numbers) in various places. But I wonder if I can
replace the one that Dr. Watson needs and will that cure my problems?

Any help or suggestions would be greatly appreciated.

Thanks,
Bob
