To be clear, I think this isn't really an OpenGL problem, but rather one related to FFI or event handling. If anyone could explain to me,The release notes for 7.0.1 said this about that flag:

There is a new -fno-ghci-sandbox flag, which stops GHCi running computations in a separate thread. In particular, this is useful for GLUT on OS X, which only works if being run on the main thread.

Worth noting is that Jesper said it *works* in ghci, and fails when compiled.... -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
