Short description of error
The text in the text editor window can extend beyond the right hand edge (with text wrap turned off), but no horizontal scroll bar exists for the window. Window does scroll horizontally if hidden text is selected or end key is pressed.
Not clear if this is a bug or just a missed feature.
