I have a subclassed FL_GL_Window into which I draw, and things works well
until I open another FL_GL_Window. The context of the second window is
NULL, as returned by context(). The viewport of the first window becomes
that of the second window (that is, a small rectangle in the lower left
corner which is the size of the second window).  

It runs without this issue on Linux. I am using FL_OPENGL3 since I am need
shaders.

The software is available should you feel inclined:
