Attachment problem with web based mail

We hired a developer about a year ago to develop a web based email system for us in php. The developer is no longer around, so I am having to pick up the development on the project...When clicking on the attachment link of an email in Internet Explorer 5.5 in Windows 98, I get the save as dialog and when I select ok, it tries to save the html page. If I right click and do save target as, it gets the correct file. This all works correctly in IE 5.0 and Netscape 4.76, and what's weird is that it even works as expected in IE 5.5 running on Win2k. Can anyone offer any suggestions? I'll be glad to send any code snipplets, or info if anyone can clue me in... Thanks in advance, Jack Davis Network Admin Bootheel Internet Services lists@bootheel.net
