I am using windows xp, visual studio 2008, and the latest freeglut.
Seems like the glutMainLoop() is stopping, when i click the title bar of my window (to move the window).
Unfortunalty if i have 2 glut windows, both hangs while i hold down the mouse
button at the title bar of any of the 2 windows.
(there is an opengl windows app that is not using glut, also hangs when the window is moved with the mouse, http://nehe.gamedev.net/tutorial/bitmap_fonts/17002/\)
