IE7 Fade animations choppy/not present with transparent PNG.

In the example if you roll over the images the fade does not take place properly in IE7. FF2 and Opera 9 display the transition correctly.

Could you make a small test case and attach it so we can quickly check this ?

Unfortunately IE7s support for PNGs is still very fragile. It is just to much to process the opacity of another element on top of a PNG. There isn't anything we can do as it is a browser/system limitation.
