Re: [wxhaskell-users] bus error

[Doaitse S. <do...@cs...>]

ad 1) It has been pointed out to me that you can call the enableGUI =20
 >> main only once; otherwise you get the problem I had

ad 2) I made a mistake in thinking that the a.out would always be =20
used. So bad reading of the instructions from my side. Sorry.
