Hi
Thanks for the reply.
I don't get an error message, just a pop up which says

Unable to open http://(name of website). Cannot locate the internet server or proxy server.

The link you sent me appears to be for a fix in Outlook, my problem is in word. I do not use outlook at all. All my emails are through Yahoo or AOL.
I will try using Internet Explorer instead of Firefox and see if that helps.
Too late tonight though, will try tomorrow.
Thanks again.

Joysie
