in reply to Tk button appearance while its callback runs

Try something like ...
$myButton->configure( background => 'red' );
... basically $widget->configure( ?arg, .. arg?) lets you change the changable options on the widget.

    This is a good idea, but the color change/configure method doesn't seem to fire on behalf of the callback until the whole callback/subroutine finishes. Which is after I've twiddled my thumbs for a while staring at a stupid sunken button while I wait for my Word stuff to finish. Sure, at that point I get the effect, but I want the effect to be concurrent with the processing of the callback, not after.
