Now I tried ist using the testgtk.c example stripped to the core of
the GtkEntry part.  I appended this as "entry.c".  I'm a little bit
confused, why the second entry (in fact ist is the *last* entry, if
you copy the few lines which create a new entry) is white text on blue
and the first (in fact all lines before the last) is black text on
gray.  Is there any sense for a special colouring of the last entry?

Please note that this colouring is independent form having the focus
or not.

The more importand problem is that this example works, but if I
want to use an entry, which I create in exactly the same manner, 
works different, that means doesn't show the wished behaviour, if
I put it into a cell of a GtkTable widget.  Do I have it to put
it into a box acting as a container and put this box into the
table that entry works right?
(I could ship an example for the table too, if the case is not
clear.)

I would consider this as a misfeature.

Kind regards

      Andreas.
