Internet Explorer 9 final was released yesterday, and Xenforo has a bug with it. It's "Enter bug", this bug appear from IE9 RC. I don't know if this is IE's bug or xenforo bug, but let me describe this bug. Like this paragraph, I have to enter to make a new paragraph. But when I submit this thread, the space line above this paragraph will disappear. You can test by downloading IE9 final here. [Some words appear here] But if you make some words in that line, it will appear. This bug doesn't happen to Mozilla Firefox and Google Chrome. This first post is posted with IE9 final.
