That's unlikely, I'm using Windows 7 and have no problem like his.
Also, I really recommend you add one more textbox the the intro when Red first appears. It looks unpolished with just Red suddenly out of nowhere and then with no prefacing going to the name screen.
It could even be be something simple like "Now, what's your name?"
One final note: Are you going to fix the huge amount of empty space on certain text boxes? This ones just a little graphical complaint, but it makes the textbox so tall it could fit three lines, which makes it look massive. I think it'd just add a touch of polish if it were fixed.
