The gray box appears in IE when someone specifies an alpha channel in the PNG -- IE can't handle the transparency, so it renders a gray background. I expect it would be the same with background images.
There's an IE 6 workaround to PNG transparency, someone else will have to tell you about it though. -- Cameron W: www.themaninblue.com __________________________________ Do you Yahoo!? Yahoo!
