Hidden attachments in mail from Outlook Express

[Larry Nolan]

I am using Outlook 2003 that communicates with an Exchange email server.

Receive mail from an Outlook Express user in HTML format with
attachments that are not shown until I do a File/Save Attachements.

If I forward the message and change the Format of the outgoing
message to Plain Text, then the attachments are shown in the message
window.

Why are the attachments not shown and is there a setting change in
Outlook 2003 or in Outlook Express (sorry don't know what version the
sender is using) to keep the attachments from being hidden?

thanks,
larry
