I had a problem and whipped up a quick solution: fade-in and fade-out a series of quotations. My solution works just as I want it in every browser except any of the IEs. The only problem with the IEs is that the text does not fade in and fade out; the text simply pops into existence.
I believe I've run into a similar problem before when trying to dynamically change the filter:alpha(opacity=xx) of an element.
Any help is greatly appreciated!
