It's worth noting this entry from the wxWidgets FAQ: wxWidgets (like most GUI toolkits underneath it) is not thread-safe, and handling of GUI components should always be done exclusively in the main thread. This doesn't stop you from doing the non-GUI stuff in other threads though. Was interested to see that the wxHaskell mutable var is just a TVar (from STM?) -- Eric Kow <http://erickow.com>
