I will have to agree with kj and Richard Fateman that this is both annoying and borderline bug. Of course there is an explanation as to why this happens but this doesn't make it correct. I know that Mathematical looks for literal occurrences when it applies replacement rules, and so I cut-and-pasted the denominator to create the replacement. Obviously what I see is not what there is. Nonetheless, when I manipulate an expression I go by what I see, and Mathematica in this case was deceitful. tm
