Downloading attachments from yahoo mail

[jonr@xxxxxxxxxx]

I am having a problem downloading attachments from yahoo mail.  
Starting in the Inbox if I click the "paper clip" for my attachment  
then click "Scan and Save to Computer" then when the scan is done I  
click the "Download Attachment" button it kicks my back to Yahoos home  
page.

If instead of doing it the above way, on the left hand side if I click  
the "My Attachments" link under "Search Shortcuts" then put a check  
mark next to my attachment and click the "Save to Computer" button, it  
then scans it and gives me a new page with the button "Download File".  
When done this way it works and I can download the attachment.

If I bypass my proxy server then it works both of the ways described  
above. Has anybody ran into this and is there a workaround, other than  
the second way described above? What is needed to help troubleshoot  
this problem?

Thanks for any help,

Jon
