Canon ScanGer and Mozilla

I have a Canon Canoscan 4200F. The scanner and the driver software are
supposed to have the ability to scan and attach the image to an e-mail
with the push of a button. The documentation says that it should work
with Outlook, Outlook Express, and Netscape. the software allows you to
add additional programs and to specify which mail program will be used.

The mail function is not working correctly with Mozilla 1.7.3, nor with
Netscape 7.1. It does scan the image, save it, and then display the
picture in the Browser, rather than attaching it to an e-mail.

Has anyone gotten this to work?
Canon support has been no help.

Thanks,
Bernie
