lighting model pandemonium

[Scott the Great]

Hi, I am writing a graphics program in a multi-windowing environment.  Strange
things are happening with the lighting model when I open and close windows.
Sometimes I get lmbind errors and sometimes other windows get darker or
lighter.  I really have no idea what's happening here.  The definition of
lighting variables for each window is a single subroutine which is ONLY
called when a window is opened...

Any ideas
