I find that in IE 6+7 if I have a div with a non background image and z index of 0, these images will be displayed on top of an overlapping div with a background colour and a z index of 2000. This should not be happening.
I've tried what you said but no change. Please see this for my problem in IE 6 or 7
The login and registered images are incorrectly placed on top of the drop down menu on the home and support button.
I would be very grateful for any further assistance you could give
Ok I have solved some of my woes. What I had to do was wrap the two divs in a relative positioned div and remove the relative properties of the main inner divs.
