I believe, (though am not able to prove), that you are running into an issue with the way Windows handles selections. I haven't figured out a way to prevent that, though you can kind of half-assed work around it by doing something like this:

use strict; use warnings; use Tk; my $mw = new MainWindow; my $lines = "Distribution ILYAZ/os2/tk/Tk-OS2src-1.04.zip Distribution INGY/Kwiki-Zipcode-0.12.tar.gz Distribution ISHIGAKI/Archive-Any-Plugin-Bzip2-0.01.tar.gz Distribution JAE/perlipse/Perlipse-0.02.zip Distribution JALYCAI/article_fetcher.zip Distribution JAME/ftndb-0.35.zip Distribution JBNIVOIT/Win32-ShellExt-0.1.zip Distribution JBRYAN/AI-NeuralNet-BackProp-0.77.zip Distribution JBRYAN/AI-NeuralNet-BackProp-0.89.zip Distribution JBRYAN/AI-NeuralNet-Mesh-0.44.zip Distribution KRYDE/Filter-gunzip-4.tar.gz"; my $entry = $mw->Entry->pack; my $txt = $mw->Text(-selectbackground=>'lightgreen')->pack; my $but = $mw->Button(-text=>'List Selected to STDOUT', -command=>sub{ print STDERR $txt->getSelected,"\n"; print STDERR "HI THERE\n"; })->pack; $txt->insert('end', $lines); $txt->tagConfigure('winsel', -background => $txt->tagCget('sel','-back +ground')); $txt->bind('<<Selection>>', sub { $txt->tagRemove('winsel','1.0', 'end'); return if !defined $txt->tagRanges('sel'); $txt->tagAdd('winsel', $txt->tagRanges('sel')) } ); MainLoop;

Create your own tag with the same coloring then shadow the selection tag. Works on windows and shouldn't cause problems elsewhere.
