[untouchable]

Howdy... I am currently working with a team to develop a MMORPG game. We are working on the client-side application and I was writing a windows wrapper class complete with a message router/handler (NOTE: HEAVY WINDOWS!!!). I am running into problems and invite anyone who can help to visit this post on gamedev:
