I've got an input field that I want to restrict users to only being
able to post as much as will fit into the field without scrolling
(approx. 500 chars). I can set the field to a max. chars of 500, but
this doesn't take into account line breaks, which allow the user to
write much less than 500 chars, but still extend past the visible box.

Try this
textField.onChanged = function() {
while (this.maxscroll>1) {
this.text = this.text.substr(0, -1);
}
}
textField.onScroller = function() {
while (this.maxscroll>1) {
this.text = this.text.substr(0, -1);
}
}
where "textField" is the name of your input field. You need to trap
both scroller and
onChanged events to make it bullet proof.
Cheers
