Perl/Tk fedora 10

[Patrick Dupre]

Hello,

I am experiencing problem with the following code: I cannot edit the
Widget. It was working fine in fc 7.
It does seem to be link to nothing to the graphics card or with.
(I changed the graphics card). However, it work on another fc10 machine.
This one has an Intel DQ965GF Mother board.

Futhermore, if you comment the last line of code:
$frame_In -> Label (-text => 'In:') -> pack (-side => 'left') ;
the widget "frame_WaveNumb" becomes editable  !!!

Is my code wrong ?

#!/usr/bin/perl -w

#use 5.10.0 ;

use Tk ;
use strict ;

my ($main, $frame_WaveNumb, $val_Wave, $frame_In) ;

$main = MainWindow -> new () ;

$frame_WaveNumb = $main -> Frame () -> pack (-side => 'top', -pady => 5) ;
$frame_WaveNumb -> Label (-text => 'Energy (cm-1)') -> pack (-side => 
'left') ;
$val_Wave = $frame_WaveNumb -> Entry (-width => 7, -justify => 'right') -> 
pack (-side => 'right') ;

$frame_In = $main -> Frame () -> pack (-side => 'top', -pady => 5) ;
$frame_In -> Label (-text => 'In:') -> pack (-side => 'left') ;


MainLoop ;
