ive implemented a draggable section of a site that allows you to drag transparent png products on to a canvas for preview.


when a user selects a product, i want to put a visual effect i.e make the product pulse by changing opacity.

in firefox this works perfectly, however in ie6 when the product pulses it produces a horrid black background on the image(see below)





ive set the background of the draggable div using IE's alphaimageloader

e.g.
.css('filter', "progidXImageTransform.Microsoft.AlphaImageLoader(src="+newSrc+", sizingMethod='scale')")




any reason why my png's appear this way?
