ad 1) It has been pointed out to me that you can call the enableGUI
>> 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
used. So bad reading of the instructions from my side. Sorry.

When trying to run even the smallert wx program in my Mac OS X

[1 of 2] Compiling EnableGUI ( EnableGUI.hs, interpreted )
[2 of 2] Compiling Main ( Main.hs, interpreted )
Ok, modules loaded: EnableGUI, Main.
*Main> enableGUI >> main
*Main> enableGUI >> main
Bus error
koshka:~/Desktop/TestWX doaitse$
So note that the first time the button appears, but the second time
I try to run it I get the bus error.
This doesn't look good to me ;-{{, but I have no idea what to do next?
The other unhealthy thing is that if I comment out the EnableGUI
and use ghc, I get:
koshka:~/Desktop/TestWX doaitse$ ghc -package wx Main.hs
koshka:~/Desktop/TestWX doaitse$ /usr/local/wxhaskell/bin/macosx-
app -v Main
creating resource:
> /Developer/Tools/Rez -t APPL Carbon.r -o Main
creating app directories:
- Main.app
- Main.app/Contents
- Main.app/Contents/MacOS
- Main.app/Contents/Resources
creating package info:
- Main.app/Contents/PkgInfo
done.
koshka:~/Desktop/TestWX doaitse$ open Main

Anyone any ideas?

Hi all
Is there anybody who has an example of using context sensitive popup
menus?
I am especially interested in an example with a listbox, where one
can
right-click an element and get a popup menu.
Greetings,
