Using the AlphaImageLoader filter on a background PNG in IE6. Looks right, but links inside the element stop being clickable. Is there a fix, or do I have to use GIFs?
Also be careful with repeating backgrounds. The filter doesn't do background-repeat or background-position, it scales or crops. For anything that tiles I use an 8-bit PNG with alpha from Fireworks, which IE6 shows with hard edges instead of a grey box.
