Interesting... as a separate file it also works for me... But in with the rest of my code, the scrolled listboxes still refuse to show up. (No I did not forget MainLoop, but I'd ask me that too) If I change $listbox1 to a non-scrolled widget... it displays. ie...

#my $listbox1=$p->Scrolled('Listbox',
#            -scrollbars=>'e',
#            -exportselection => 0
#            )->place(-anchor=>'nw',
#                -x=>"50",
#                -y=>"150");
my $listbox1=$p->Listbox()->place(-anchor=>'nw',-x=>"50",-y=>"150");  
+          
                
    $listbox1->configure(-height=>'35', -width=>'25', -selectmode => "
+browse");

It just does NOT like the scrolled option. I'm running ActivePerl 5.10.0.1004 on a WinXP machine btw.
