I have several widgets displayed including a scrollable listbox and some scrollable text boxes. If a user clicks in one of my textboxes and begins to use the down arrow key when the textbox is empty, perl throws "Use of uninitialized value in numeric ne (!=) at ...Text.pm line 1223" I tried to duplicate this with a small example, but 
use Tk;

my $mw = MainWindow->new();

$mw->Scrolled('Text')->pack();
$mw->Text()->pack;
MainLoop;

does not display the problem for either the Scrolled Text or the simple Text, so I figured the problem lied in my personal bindings of <Up> and <Down>. I removed the bindings and it stilled was there. I was able to duplicate the issue using the widget demo "widget". If you run "widget" and click on "1. Basic editable text." and delete all of the text in the text widget. You can replicate it by now down-arrowing. Anyone seen/solved this before I start digging around into how Nick/Greg handled this binding?
