I've seen this before, but now I can't find the article that describes how
to
fix it. On my wife's computer, using XP home and OE 6, every time she
tries
to send email, a box pops up with the preparing to install notice which
she
has to cancel numerous times before the email is finally sent. The last
box
reads something about spell checking has been halted and do you want to
send
anyway? I know there is a fix for this, but I can't find it.
Thanks,
John
