Windows XP, Outlook 2000. When I reply to a message and compose some text,
I have no problems. But, when I attempt to edit any of the text contained
in the original message, and press the space bar or any of the alphameric
keys, my name is immediately inserted like this: [Bob].

For example, if I received the above paragraph in an email and then replied
to it, and tried to insert a space between "Windows XP" and the ",", what
would appear is: Windows XP [Bob] . Why does Outlook do this and how do I
stop it?
