Hi,
the bug you describe seems to appear on windows only. It can be boiled down to the following example. Also this workaround is a bit more 'general-purpose' as it does not require the widget to be managed by the 'pack' geometry manager:
use strict;
use warnings;
use Tk;
use Tk::Text;
my $mw = tkinit;
my $t = $mw->Scrolled('Text',
-scrollbars => 'osoe',
)->pack;
$t->update;
$t->insert("insert", sprintf "%3d. Text Text Text\n",$_) for(0..64);
$t->update;
# force scrollbar refresh:
# my $sb = $t->Subwidget('yscrollbar');
# $sb->set( $sb->get );
MainLoop;
Cheers, Christoph

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
