Hello. I have a perl/tk gui working to some degree of satisfaction, but this is my first attempt. I have successfully executed a program, however a problem occurs when the "program2" tab is selected and the window is resized. The tabs seem to disappear. Any ideas? -- The purpose is a simple front-end to several standalone programs which run from scripts. If there are any obvious flaws or pitfalls, please mention them.

#!/usr/bin/perl -w
use warnings;
use strict;
use Tk;
use Tk::NoteBook;
require Tk::Pane;
use Tie::IxHash;
use Tk::LabEntry;

my $mw = MainWindow->new;
$mw->geometry( "600x500");
$mw->title("Survival Kit");
