Okay, part of our custom filter system (which uses a cookie in addition to a host of other things) is reacting badly (meaning it won't work) with WMV files embedded in Firefox. It works perfectly with all four other main browsers in both MOV and WMV formats. It works fine with MOV in Firefox. But the WMV, just spin and spin and never play. Any advance programming folks with tips? I have exhausted all the tech forums and thought I would give it a shot here.
