There are at least 2 major bugs with PNG support in IE7 at the moment.

1.) The Gamma is all wrong, meaning all images are darker than they should be.
2.) Transparency fails, if overlaid over any background that is also set to transparent.

Since the whole issue with PNG support that we complained about in IE6, was the lack of full alpha transparency, I see the current implementation as only half way there.
