[Haskell-cafe] ghci + hopengl

[Duane Johnson]

I've had issues with ghci and opengl... I usually have to compile my  
programs before they will run.  I'm not sure why that's the case, but  
I too get strange window behavior (sometimes it freezes, other times  
it doesn't even show up).

If you're on a Mac and would like help compiling to a .app folder, let  
me know and I can post how I did that.

Regards,
Duane Johnson
