I've never had a problem before with IE 7 or 8 and transparent PNGs until now. I don't know if it's Photoshop or Fireworks that is possibly messed up.
I really don't know what else to say..
here is the link: http://michaelpstone.net/mannelaw
It's the three fading images on the home page.
My only guess is that it has to do with the content background being a transparent PNG too.
I've also downloaded pngcrush and I actually can't even get that to run in command line, so any help with that too would be nice.
Thanks in advance!
