Hello.  This is the weirdest problem I have ever seen.

Here's what happens.  I don't think code is needed, but if you wanna see the
function, let me know.

This one equation screws up the whole thing...
var = (color1-color2)/(x1-x2);

If I don't test to make sure that x1 != x2 before I use this equation, my
memory gets all weird or something.  (My triangle gets all big and weird
looking).  I should get a FPE, shouldn't I, if there's a divide by 0?

Isn't this a problem with my processor then?  The processor gives the FPE,
right?

Anyway, if I do test to make sure that x1 != x2, it works fine.

What's wrong here?
Mark
