I had mcafee anti-virus installed. I uninstalled it and installed the
anti-virus and firewall software my isp, charter.net, provides and the
problem went away. It appears to be a mcafee problem. I hope my new
anti-virus software is at least as good.
Thanks for replying.

With Outlook closed, try deleting the file extend.dat, found in the (usually
hidden) folder
%UserProfile%\Local Settings\Application Data\Microsoft\Outlook (for WIndows
XP/2000) or, I believe, %UserProfile%\Local\AppData\Microsoft\Outlook for
Vista.

Same problem, meaning exactly the same error, mentioning the same DLL
(naCmnLib71.dll)? If not, then it's not the same problem and you should
post in a separate thread.
