I have a new install of 5.0.6 GA, I've noticed that when our sales guys get quotes from Dell they come through as .html files. Using the web interface in Firefox 2 or 3, if you click on the attachment the file will open a new tab that is completely blank. If you click on download instead of the file then it downloads and you can open it in the browser just fine......

Anyone have any idea how I can get it to work like other attached files so the sales guys can click on the file attachment to open it?

TIA
