Hello,

I have a GUI program that when I compile it and run it there are no
problems.  When I load it into GHCI and type, "main", it loads the
main window but there are no window decorations and the program hangs
to the point where I have to kill the ghci process.  You see a
spinning cursor when you mouse over the window.

I don't know if this is the same issue, but it sounds like it at first glance:
