Hi,
I am a beginner. Help me.
Here is my "main.hs", sample code from the book HSOE.
----------------------------------------------------------------
module Main where
import SOE
main = runGraphics (
      do w <- openWindow "My First Graphics Program" (300, 300)
         drawInWindow w (text (100, 100) "Hello Graphics World")
         k <- getKey w
         closeWindow w
      )
------------------------------------------------------------------
When this is run, a window pops up but it immediately crashes.
I call "main" function after loading the above src file (main.hs) in
ghci
Does the same happen when you compile with "ghc --make" or use ":main"
in ghci? ghc and ghci behaving different[1] wrt. ffi calls isn't
unheard of.


[1] meaning that ghci fails
