At one point, this worked in our app.  When the user had the editor in full screen (using the "Fit to window" button,) if they clicked the Save button, the editor returned to full screen after postback.  However, about the time I hacked around the issue of not being able to get at the "getHTML" method of the editor when in a DIV set to "display:none," this behavior changed.  Now, the exposed editor instead fills just the parent DIV that it is in.  The scroll bar on the left of the IE window goes away, though, until the "Restore down' button is clicked.  Clicking the "Fit to window" button will then properly fill the screen.

 

Any ideas on what I might have changed that would cause this?
