I'm running XP Pro (SP3) and Outlook Express 6.00.2900.5512
(xpsp.080413-2105), set to send email in HTML (plain text for newsgroup
postings, HTML for email).

When I send a message to my friend (who's on an address)
it
is successfully delivered into her webmail inbox (she doesn't use OE) but,
when she opens it
there's no text in the "body" of the email, thereby making it look like I've
hit the "Send" button before typing anything. If she then clicks the "Reply"
button, my original message appears and she can read it.

Any idea what's going wrong and how we fix it?

Thanks,
Pete
