1. Your example was not complete. I had to add code to get it working.
2. You're using quite an old vtkFlRenderWindowInteractor. When
reporting problems, make sure you're using the latest.
3. In this case, you were lucky. ;)
It seems that after a FLTK hide()/show(), nobody takes the time to
ensure that there's a valid GL context. This happens later during FLTK
drawing, which in our case doesn't apply. I've added appropiate calls
to the vtkFlRenderWindowInteractor code to make sure that there's always
a valid context.
