 .. My experience above causes me to wonder if 'BGselect' could be made by
inverting the L*a*b  values before interpreting them; maybe something to try
after 2.4.


I do not quite understand your problems.  I am an aloof developer who
has serious problems to understand user's problems. Please help me
out, maybe I am misunderstanding something? So please do not get me
wrong here.

What one defines foreground or background is not a matter of the tool
but a matter of the human being who is using the tool.

I cut out the windows selecting them all with the lasso.
See: http://www.gerald-friedland.de/tmp/multiwindow_sel.png

Then I disabled contiguos because the Windows in this image are not
connected (may be "disconnected" would be a better string?).

Then I needed a few foreground strokes, mainly to select the KDE
toolbar (or was it GNOME) and to include all the colors shown in this
GIMP tool dialog.

The result is then: http://www.gerald-friedland.de/tmp/multiwindow_cutout.png

If you want to have the screen-background instead of the windows, use
"select/invert" and you get the background instead of the
foreground...

No need to fiddle with color sensitivity....?

Greetings,
Gerald
