Hmm, maybe this was related that I was accidently unsubscribed
from this list for a few months.. :-(  Well, hopefully I'll listen
better from now on. However, I will have little time till October,
afterwards I'll be doing more development work again.

Great.

First of all, I strongly recommend wxWidgets 2.4.2 since it is the only
version that works with ghci. Newer wxWidgets version use static
initializers that are not properly desctructed when the dynamic
link library is not re-loaded. Furthermore, there doesn't seem to
be that many new features useful on Windows.

These are "innocent" warnings -- wxHaskell still uses the deprecated 
interface.
It would be nice to upgrade though ..

Hmm, not good -- it is even my own code :-) An easy fix would be to 
disable the odbc
when building wxWidgets (./configure --disable-odbc).

However, I have build wxHaskell with odbc on Windows -- but I was using 
Visual C++ 6.0.
So, if you have visual studio, I recommend building it using the visual 
studio
project. It is all explained in the build guide. With wxHaskell, you 
would do:

 > ./configure --with-msc  [--wxc-libname=wxcd]

open the visual studio project wxc/wxc-2.x.dsw
build the dll

 > make


Anyways, I'll try to look into it -- it seems that the make commands for 
newer
wxWidgets is lagging behind (on Linux and MacOSX I normally build with 
odbc enabled).
