Subject: Bug in WIN_BACKGROUND_COLOR for Textsw ?

Hi,

Below is a small (?!) C-program to demonstrate a problem I'm having.
When you press a LEFT or RIGHT shiftbutton, the background colors
from the two textsw are set. This works fine as long as you do not type
text into the windows. When you do and then change the colors 
the margin before the text gets the wrong color (color[0]).

Is this a bug or a feature?

Joep
