that example didn't work for me either. Sorry about not posting working code. Here is some simplified code that is based off your example, but still gives the exact behavior I described. The table loads fine, but the scroll bar doesn't work and when you sort by a column it empties the table.

use warnings;
use strict;

use Tk;
use Tk::Pane;
use Tk::NoteBook;
use DBI;
use Tk::MListbox;

### Build Main Window #
my $mainWindow = MainWindow->new;
   $mainWindow->geometry("800x600");

 my $frame = $mainWindow->Frame(-bd => 2, -relief => 'raised')->pack(-
+expand => 1, -fill => 'both');

 my $scrolledMListbox = $frame->Scrolled(
              qw/ MListbox -selectmode browse -scrollbars oe /
              )->pack(-expand => 1, -fill => 'both');


 $scrolledMListbox->columnInsert('end',  -text=>'Date', -sortable=>1, 
+-width => 10);
 $scrolledMListbox->columnInsert('end',  -text=>'Time', -sortable=>1, 
+-width => 10);
 $scrolledMListbox->columnInsert('end',  -text=>'Property', -sortable=
+>1, -width => 10);
 $scrolledMListbox->columnInsert('end',  -text=>'Name', -sortable=>1, 
+-width => 10);
 $scrolledMListbox->columnInsert('end',  -text=>'Address', -sortable=>
+1, -width => 10);
 $scrolledMListbox->columnInsert('end',  -text=>'Phone', -sortable=>1,
+ -width => 10);


  $scrolledMListbox->bindRows('<ButtonRelease-1>',
    sub {
        my ($w, $infoHR) = @_;
        print "@_\n";
        print "You selected row: " . $infoHR->{-row} .
             " in column: " . $infoHR->{-column} . "\n";

    print  $scrolledMListbox->getRow(  $scrolledMListbox->curselection
+()->[0] ),"\n";

    }
);




  for (my $count = 100; $count >= 1; $count--){

     $scrolledMListbox->insert('end', [[int rand 20], [int rand 20], [
+int rand 20], [int rand 20], [int rand 20], [int rand 20]]);

  }

It's basically the code I am using except I stripped out the database stuff and just went with a random number generator. I pulled the font stuff out because it was throwing an error and I didn't feel like debugging it.
