This is FLTK 2 code, and I can only guess, but maybe this can
help. Either don't make the windows non-modal, or use the FLTK 2
child_of() method to achieve what you want.

hiding the window is not necessary here.

The following lines establish a window hierarchy. You can probably
work against it by adding one line (see below):
> main_data_window->show();
> compass_window->show();
ack_window->child_of(main_data_window); // make it "child of" the
main window
Note: I'm not a FLTK 2 user, and maybe the syntax is wrong.

If the above doesn't help, then you can hide both windows and then
show the one you want, because this will (probably) create the correct
window hierarchy again, but I'm not at all sure about this, because
there might still be the child_of() relation. You may need to reset
it or make it explicit, as suggested above.
