[l2h] Latex2HTML converting - to \Gamma in superscript

[unruh]

I am having problems with latex2html converting a minus sign in a
superscript to a capital Gamma.
See the page
http://axion.physics.ubc.ca/q-fft/q-fft.html,
See the Quantum Fourier Transform section-- eg equations 3 5 6 7 etc.
All those capital Gammas are supposed to be minus signs.  Any clue as to
what is going on here (mandrake 6.1, with the stock latex2e,dvips, etc.)

Thanks
