This is so weird. It has been happening with one particular person.

In my addressbook I have Mary (I made up the name)
I send her an email and I get this AOL message in big orange
Letters, opps you made a mistake (something like that) and when it
Shows me the email address the letter D is added after .com and
Other times other letters are added. So I got to "mail sent" and resend it and it's okay now.

My address book this time had the right address. Before when this
Happened it had two addresses for her. It only happens to this one
Person (so far)

I did AOL LIve help and they couldn't grasp what I was saying.
Even the fact that the message was different then their usual messages.
