Rails - Nov 2005 - Send_file and Firefox

Hello,

I am trying to use send_file in my controller to serve up specific
content: (.doc, ..xls)

Seems to work fine in IE, but in FF (1.0.7, on Windows) after the file
d/ls and the app (MS Word, MSExcel) opens up with the content, a blank
window comes to the front (gets focus).

Any idea how to prevent this?

Do I need a redirect_to after the send_file in my controller''s
download_file action?

Thanks
