742	HGL broken on Windows	guest		"The following program (example from ""The Haskell School of Expression"") runs very slowly, often taking a couple of minutes to create a window:

{{{
import Graphics.SOE
main	=	runGraphics (
			do	w <- openWindow ""Hello"" (300,300)
				drawInWindow w (text(100,200) ""Hello world!"")
				k <- getKey w
				closeWindow w
		 	)
