- Create a GUIText and in the Text field write something and commit that by pressing Enter.
- Click somewhere in the Text field again and type something else
- Press Escape

Expected: the last changes are not commited and the Text box is deselected and not editable (this is what happens in Unity 4.2.1)

Actual: the last text changes are reverted (sort of like Undo) and I can continue editing. If you typed something and then clicked in some other part of the text and typed something else, pressing Escape twice will Undo those changes (unexpected behaviour)
