title: problem running wxHaskell (Windows)
body: <p>The page: (http://en.wikibooks.org/wiki/Haskell/GUI) describes that to run wx code, one can install wx and then one must "register wxHaskell with GHC" - but I think the binary installer of wxHaskell (http://wxhaskell.sourceforge.net/download.html) does that automatically?</p>
  
  <p>I installed wx-config, and then wxPack, and wxHaskell. and then did cabal install of wx and wxcore.  I am running some wx demos from Leksah, which seem mostly good - but they had some weird errors (I found an alleged solution to that: "wxhaskell-labels-cant-display-full-text"), but I wanted to try some things just from GHCi.</p>
  
  <p>I try to run their simple demos, and the the errors:</p>
