Sorry if the translation literally Google may have made this mess.
But now I think you understand the problem.
Yes is the mouse click that occurs.
In a list in which the beginning lines are short (short code) the horizontal scroll bar does not appear.
But to list the lines below and if there is a line that contains more characters than the window can display appears the horizontal scrollbar moving up the vertical bar as in picture 2.
Now if u open the notepad Microsoft empty and disables word wrapping noticed that the two scrollbars (horizontal and vertical) but come off.
Thus the estorar window size bars are activated and remain with their buttons in the same place.
Suggest that SCITE behave in the same way that the noutepad (with bars disabled) and activates them when needed.
