[wxhaskell-users] No text displayed in widgets

[Stefan H. <st...@cs...>]

I have a problem with wxHaskell (checked out from darcs a week ago)  
running on Mac OS X 10.4.8: my GUIs refuse to display any text at all.

For instance, the following program,

 > import Graphics.UI.WX
 >
 > main :: IO ()
 > main =  start gui
 >
 > gui :: IO ()
 > gui =  do
 >   frame [text := "Hello"]
 >   return ()

yields an empty frame with *no title* shown in the title bar.

Likewise, GUIs that feature buttons, labels, etc., display empty  
widgets, i.e., without the texts.

Is this a known issue? What can be done about it?

Cheers,

   Stefan
