do you get only 4 lights in both windows or is only the second one
affected? Are the lights near the root of the scenegraph or in some
branches (i.e. is it possible that lights are affected by frustum
culling branches of the graph or a bad frustum on the orthogonal view)?
Do you use the same RenderAction instance to render both windows (maybe
some state is not cleared between the two windows and you run out of
OpenGL light indices?
Sorry, as you can probably see from these questions I don't have a very
good idea what might cause this. A GL debugger (e.g. bugle or
glIntercept) may be helpful to determine which light related OpenGL
state is being set and in what way it differs in the error case.
Cheers,
Carsten
