   Opening a new GLUT window after leaving main loop
  Hi all, I'm a beginner in OpenGL programming and I found GLUT very useful to easily build simple POGL ( Perl OpenGL ) applications. But I have a problem: my script opens up a window then when I exit the window I return from the glutMainLoop and continue with the code. Then I want to open a new GLUT window but I can't call glutInit again and also if I don't call it when I call a GLUT function, for example glutCreateWindow, I get the following error:Function <glutCreateWindow> called without first calling 'glutInit'What's the best way to deal with that?Thank you for your help!
