So you never saw any style issues apart from one small error (....text is translated in ajax editor (as I described before it is already solved in 4.4.0 but layout is OK - no css issue.)? I find that difficult to believe. I saw them in Chrome, Opera, Safari, IE and FF. I looked at this for hours before starting the thread.
You haven't said whether you were able to reproduce the symptoms I described. Did you follow my steps in post 19?
