Hypergeometric rational/real discrepancy (bug?)

Any reason why these 2 lines should produce such different results:

Hypergeometric2F1Regularized[1, m - 2, m + 1, x] /. {m -> 1, x -> 1}

Hypergeometric2F1Regularized[1, m - 2, m + 1, x] /. {m -> 1, x -> 1.}

I'm using Mathematica 4.1 -- same result on Linux, Solaris, and Windows.

Thanks!
Daniel

seems today."  -- Stephen Wolfram, creator of Mathematica
