Hi,
First some background:
Distribution name and version: Tk-NoteBook 4.011
Perl version: This is perl, v5.8.8 built for MSWin32-x86-multi-thread
(actually ActiveState Perl 5.8.8 for Win32)
Operating System vendor and version: Windows XP Pro ver. 5.1 Service Pack 3
In the documentation for Tk-NoteBook it is stated, "The widget takes all
the options that a Frame does.". However this does not appear to be the
case. Case in point, instantiating a new NoteBook and including size
options fails:
my $Mw = MainWindow->new(-title => $0);
my $Notebook = $Mw->NoteBook(-width => 500, -height => 500)->place(-x =>
1, -y => 1);
Gives:
Tk::Error: Can't set -height to `500' for Tk::NoteBook=HASH(0x3cedd08):
Bad option `-height' at C:/perl/site/lib/Tk/Configure.pm line 46.

It is also not possible to instantiate a tab with said options:
my $Tab_1 = $Notebook->add('tab_1', -width => 500, -height => 500,
-label => 'Tab No. 1', -state => 'normal');
Gives:
Bad option `-height' at C:/perl/site/lib/Tk.pm line 250.
However, it is possible to configure the size on the tab object reference:
$Tab_1->configure(-width => 500, -height => 500);
Works just fine.
Finally, this post 'configure' does not also work for the NoteBook
reference:
my $Mw = MainWindow->new(-title => $0);
my $Notebook = $Mw->NoteBook()->place(-x => 1, -y => 1);
$Notebook->configure(-width => 500, -height => 500);
Gives:
Tk::Error: Can't set -height to `500' for Tk::NoteBook=HASH(0x3cec578):

If this post-configuration is the way NoteBook tabs are meant to work
then it seems poorly documented.
