OK??

So, after really getting down and dirty, replacing code with previously tested code in different sections and completely substituting the entire current structure of the prototype with the old one to make sure that the problem was in that code I finally figured it out.

IT WAS ShowCursor(true);

Don't ask me how the hell this was making everything corrupt, but it was, I don't get it?? Who'd a thought. I use that call in other places and have never had that problem before.
