When a button is in the disabled state it does not respond -as advertised, but once the button is enabled again it responds to all presses that it received when it was in the disabled state. I can't figure out how to eliminate this behavior. I do not want the button to respond to anything that happened when it was disabled -ever. Can anyone help me with this? Here's a program to demonstrates the problem, it disables all buttons for 4 seconds whenever one is pressed. Thanks

use Tk;

my $mw = MainWindow->new;

my %btns;
for (qw(alpha beta gamma)){
    my $name = $_;
    $btns{$_} = $mw->Button(
        -text => $_,
        -command => sub{foo($name)},
        )->pack;
}

MainLoop;

sub foo{

    my $name = shift;
    for (keys %btns){
        $btns{$_}->configure(-state => 'disabled');
    }

    my %dispatch =(
        alpha => \&alpha,
        beta => \&beta,
        gamma => \&gamma,
        );

    $dispatch{$name}->($name);

    for (keys %btns){
        $btns{$_}->configure(-state => 'normal');
    }
}

sub alpha{
    print "alpha\n";
    sleep 4;
}
sub beta{
    print "beta\n";
    sleep 4;
}
sub gamma{
    print "gamma\n";
    sleep 4;
}
