If you downloaded v1.3 of jquery.flash I would recommend switching to this one. There has been no functionality changes, so it should just be drop-in. It fixes a minor bug I added when I switched to using indexOf() for iterating through attributes and parameters…apparently IE doesn’t support it. >.>
That’s fixed now and I did a few minor structural changes to reduce the character count a little and make things ever so slightly speedier. I also created a fancy tutorial page type thing for it, which you can check out here.
