It seems like when you start the game, it defaults to entering your screen name, rather than the one that's actually in the text box in which you type your name for a high score entry. I have to retype my real name (Steven) or else it enters my screen name (GPro44), even though I don't have that in the text box. After I retype my name, it works fine. But I shouldn't have to do that in the first place.
If there's a bug, YO! I'll report it!
