also, when inn editing mode, use smaller stage mode.
Cute. It seems to go on forever (or at least I lost patience before it ran out) vertically, but not horizontally. (I say this not having read the code...)
thank you!
that's what happened 
bump i guess?
Are you wanting someone to do something in particular, or just review your work?
PS Also, your original post was three days ago! Bumping is for when a month has gone by with no response.
