Duplicate emails sent when sending photo attachments

Whenever I use XP's feature of "email this photo", outlook
express sends two identical emails to the recipient.

I've done a lot of tests and have discovered that if you
do not have outlook express open while doing this, it
works fine (only one email gets sent). If you have
outlook express open when you send the photo, two emails
are sent.

Am I missing a setting or something? I've read thru this
newsgroup and have noticed others having this problem, but
I could not find a solution.

This happens with multiple photo attachments or a single
attachment. It happens regardless of the size of the
attachment.

Any ideas? It's a pain having to close down outlook
express each time I want to use this feature of XP.
