Okay, my patch worked if you weren't using a different maths font,  
because those two lines above prevented the code from running if  
euler.sty or lucbmath.sty had taken over.

If you remove those two lines from the patch (the first and last),  
then things *might* work, but then again, euler and lucbmath might  
not then behave exactly as expected.

Maths in LaTeX seems to be built like a card tower...just a little  
sneeze, and everything falls down. We might have to end up writing  
custom maths font packages.

I'm still confused where things are broken, though.
