Funny, I had commented out the two lines in the stylesheet which referred to the header_bg, but IE was still showing it, even though all was kosher in FF.

Even stranger, view source in IE did not have any reference to header_bg in the file. So it was displaying it, but wasn't part of the source?? It wasn't a cacheing issue either. I had to actually delete the two lines for IE to play nice.

I hate IE.
