Hello,
I'm having a little fun playing with perl/tk on an NT4 platform. I seem to be having problems closing Tk::Toplevel windows as part of a -command switch for button widgets. When the add button on the addgroupswindow is pressed, addgroups() is run, but the addgroupswindow toplevel is not destroyed. 
use Tk;
use Tk::DialogBox;
use Tk::Dialog;
use Tk::Label;
use Tk::Entry;
use Tk::Tree;
use Win32::Process;

my $Mainwindow = MainWindow->new;
#?
my $firstname = $Mainwindow->Entry 
    (-width=>30);
$firstname ->grid(-row => 0, -col => 1);
#?
my $groupstouserbutton = $Mainwindow->Button
    (-text => "add to groups",
    -command => sub { addgroupswindowmaker($firstname)});
$groupstouserbutton ->grid(-row=>19, -col=>1);
#?
my $quitbutton = $Mainwindow->Button
    (-text => "Quit",
    -command => [$Mainwindow => 'destroy']);
$quitbutton ->grid(-row=>20, -col=>1);
MainLoop;

sub addgroupswindowmaker
{
$addgroupswindow = $Mainwindow->Scrolled(Toplevel,
            -scrollbars => 'osoe');
        $addgroupswindow->title("Potato");
#?
my $addgroupsbutton = $addgroupswindow->Button
            (-text => "Add",
            -command => sub { addgroups();$addgroupswindow => 'destroy
+'})->grid(-row=> $k,-col => "1");
        my $cancelgroupsbutton = $addgroupswindow->Button
            (-text => "Done",
            -command => [$addgroupswindow => 'destroy'])->grid(-row=> 
+$k,-col => "2");
}
sub addgroups{
#?
}
