I've got a similar problem with Fax and Scan with my Windows 7 Ultimate. I just finished composing a fax that had 4 jpeg attachments. When I try to send it, I get: "Windows can't fax or preview the attached file type.Try installing a program that allows you to print .tif files, save the attached file as a .tif file and try again." Windows Picture Gallery opens tif files with no problems, why would I need to convert this to a tif file anyways? I'm getting pissed!
