My machine running XPH-SP3 has both Windows Live Mail and OE6 on it. Recently
I have had severe problems sending *.pps or *.wmv attachments from OE6. For
some reason when sending the attachment is broken into several pieces, and
arrives at the destination as those several seperate e-Mails - all unusable.

This problem appeared not long after I upgraded to IE8.

This machine still has OE6 as Windows Live Mail still doesn't allow for
distinct identities (as yet).

Suggestions?
