I'm the one who posted the problem earlier and someone gave an answer. Unfortunately his method did not work either. I do not know the purpose of your game or application but in case you wanted to create a game with it: forget about it. My purpose was to develop a map editor which fit in my own needs and therefore the windows forms input event handles were more than enough for me but if you were planning to create a game: forget it. This is a internal bug within the IO class that just need to be fixed in the future. Right now there is not anything you can do about it..
I hope this helps you
Nothing to tell, really.
