[Haskell-cafe] Terminating GLUT/GLFW programs

[hjgtuyl at chello.nl]

L.S.,

I am trying GLUT and GLFW (on Windows XP, with GHC 6.8.2); the sample  
programs do not terminate when I close the window by clicking on the cross  
in the upper right corner of the window.

The sample program for GLUT is at
   http://blog.mikael.johanssons.org/archive/2006/09/opengl-programming-in-haskell-a-tutorial-part-1/
the GLFW program:
   http://haskell.org/haskellwiki/GLFW

I tried in the GLUT program:
   close = exitWith ExitSuccess

   closeCallback $= Just close     -- => User error (unknown GLUT call  
getCloseFunc, check for freeglut)

this needs freeglut (not documented); I downloaded freeglut.dll and placed  
it in the windows\system32 directory. The error message remained.

What is needed to let these programs terminate properly?
