I'm having the same problem...we both got a response from christopher, I
tried his suggestion, but it does not work...has it for you?

When I create a flat contour chart, XL insists on making all the areas
teselated surfaces so that I get shadowing of the areas instead of a steady
single colour. I want to turn this off and get a single colour for each
contour level (like all the XLs before 2007). I can't figure out how to do
this. Can someone help me.
