4Chan Greentext Editor(Updated)

So I noticed a pretty large bug that I apparently didn't see --- After
reaching the size of the textbox(As in, making text which fits the
textbox size itself) going past that last line which makes the textbox
have a scrollbar will cause further lines to make the textbox 'Jerk up'
as a result of the Regex.

In order to combat this I have made the form itself larger, but this
also meant having to go and make an entire new background.

Now you should be able to work fine with it, atleast until I can find a
way to fix the bug itself without having to use this cheap workaround.

But really though, it only starts doing it once you're around say, 1900+
characters, so at that point you should be clearing the box(or post?)
anyway to make the next part. Or something.

Sorry about this.
