Yes, I suspected something like this was happening.  I ended up adopting
Mandar's suggestion of writing a beamer.el file and placing it in my
TeX-style-private directory (I think that's the one I need).  This has the
advantage that I can format the frame insertion the way I want and don't need to
issue any commands to fix the formatting.

Thanks everyone!
