[Haskell-cafe] Code from Haskell School of Expression hanging.

I'm using the OpenGL stuff (GLFW). Same set of problems?

It might be that you need to compile the code. And even then, perhaps it 
doesn't run correctly in ghci, iirc, gtk2hs used to not run in ghci (some 
threading issues, I'm not sure whether they've been resolved), maybe the 
graphics library used by HSOE has similar issues. Try and hope for the 
best.
