[Haskell-beginners] help with type error in a wxHaskell program

[David McBride]

The type of frame according to the documentation is frame :: [Prop
<http://hackage.haskell.org/package/wx-0.92.1.0/docs/Graphics-UI-WX-Attributes.html#t:Prop>
(Frame
<http://hackage.haskell.org/package/wx-0.92.1.0/docs/Graphics-UI-WX-Frame.html#t:Frame>
())] -> IO
<http://hackage.haskell.org/package/base-4.8.1.0/docs/System-IO.html#t:IO> (
Frame
<http://hackage.haskell.org/package/wx-0.92.1.0/docs/Graphics-UI-WX-Frame.html#t:Frame>
()).  Maybe the documentation you are looking at is out of date?
