So, recently (past few days maybe) the text box when making a new post or thread has expanded to fill the whole screen from the menu bar all the way over to the far right side of the screen. It used to be a set width, just enough for the "Bold" to "Spoiler" buttons to fit. My desktop is 1680x1050, the text box is about twice the width of the area taken up by the markup buttons.
