First thing that comes to mind is $widget->focus;

I think you should "simulate" switching forth and back to
enabled/disabled before actual work.
Such tricks, when do not work with suggested "update", they usually work
with "afterIdle" call.
HTH.
Vadim.
Hmmm, using afterIdle didn't work either...
Further investigation indicates that you need to
have the flashing text cursor bar, flashing in the
text window for selections to work at all (doesn't
matter if state=>'normal' or state=>'disabled').
Seems like the 'insert' mark has something to do
with this.
You can test this latest theory with the following code:
use Tk;
my $mw = MainWindow->new;
my $text = $mw->Text(-state=>'normal')->pack;
$text->insert('end',"one\ntwo\nthree\nfor\nfive\nsix\nseven\neight\nnine\nten\n");
$text->mark('set','insert', '1.1');
$mw->Button(
-text => "selectall",
-command => sub{$text->selectAll} )->pack;
MainLoop;
1.) When text window comes up, click on the selectall
button. On my PC, nothing is shown as selected.
2.) Now click somewhere in the text, so you have
the flashing text cursor bar.
3.) Now click on the selectall button. On my PC
everything is marked as selected.
Any other suggestions?
Thanks
