Color

[Ricardo Cantu]

It seems that once data has been keyed into a field, the keyed in
data can not have its color changed.. 
In the following example, when you first enter a field I want the color
to be SEL, then when you start typing I want the color to be HIGH, then after 
you leave the field I want the color to be NORM. But the color of the keyed 
in data stays HIGH even after doing a  set_field_back(current_field(my_form), 
COLOR_PAIR (NORM)) on the field. Is there a way to change the color of 
already keyed in data?
