Zero length vectors causing problems

[Tom S. <to...@as...>]

Hi,

I am getting a lot of Exceptions like this:

"MyApp caused an exception of type 10H in module Quesa.DLL..."

when running Quesa on a Windows 98 machine. I believe that they are caused by passing zero-length vectors or zero-size polygons,
which I imagine might cause Quesa to try to divide by zero.

It is difficult to eradicate all possibility of a zero-length vector from my program. Is there a way to get Quesa to just ignore
zero-length vectors and zero-size triangles / polygons?

If they are all divide-by-zeroes could the '/' operator be somehow overloaded to check first?
