auto

When a text is a paragraph, the content may be the first row, second line. The third line may be in the 200 word wrap.
To the fourth row, or the first five probably in 170 word wrap the automatic, I do not know why, I use ckeditor source functions, the text is compact, no other character

My browser is IE7.0. but I have tired to run in firefox, it works well.
if the ckeditor is developed for firefox?
