There's also gtk_fixed_set_has_window(); but I think the problem
is slightly different - the problem is that button widgets no 
longer draw onto separate windows, so the button widget will never
appear *above* another child of the fixed which has a separate
window.

You may have best luck drawing using
gtk_fixed_set_has_window(fixed,TRUE) 
then whatever you were drawing on the drawing area directly
on the GtkFixed.
