Hi, Smitee and TheOldMan
I tried to do as you (Smitee) instructed, but was not successful. I got some drawn-out message after typing/entering the command, that the command "...refers to a location that is unavailable...it could be on a hard drive in this computer...check to make sure the disk is properly inserted, or that you are connected to the internet (I was)..."
I'm tring to do as instructed in one of the links posted by TheOldMan, but am having some trouble finding all the right pieces-parts to edit in the registry. For example, the Microsoft article Q248005 Method 1 instructs to edit the reg key HKEY_CURRENT_USER\SOFTWARE\Clients\Mail. But my key lacks Clients so I didn't proceed. I did see it all under the Local Machine key, though, but didn't fool with it.
I'll continue to investigate the other recommendations offered in "A special note to Prodigy users" by link provided by TheOldMan. Thank you again! Fear Not
