Having trouble working with relative cell references and my formulas. I can get my brain around the new R1C3, etc. numbering scheme vs. A1, B3, etc. But Excel 2010 has labeled one of the cells "TOP" through no action of mine. And it won't go away, and my formulas are all messed up when I autofill, it won't let me change it back to R2C2 or whatever it should be. How do I kill this zombie feature?
