Dear monks, I have a problem with perl Tk application. I'm using a getOpenFile widget wich works fine. But there is an issue if I select the file using a double-click. The file picker dialog opens in front of the main window, then I select a file by double click, the file picker dialog closes and returns a selected file, but now comes the problem: main window recieves one additional click. Sometimes this click hits a button so an action may start unintentionally. Is somebody there who experienced this problem already? Thank you. I'm using Windows 7 64-bit with StrawberryPerl 5.12...

here is a code which reproduce a problem easily (cause of the huge button) it's easy to place the file picker window over this button and select a file using a double click. A message box opens after the huge button has been clicked to inform you. 

#!/usr/local/bin/perl -w

use strict;
use warnings;
use Tk;
use utf8;
use v5.12;




my $mw = Tk::MainWindow->new(
        -title => 'main window',
        );
        
        
#Exit when the escape key is pressed
$mw -> bind('<Key-Escape>', sub { exit });

my $frame = $mw->Frame(-borderwidth => 3)->pack( -fill => 'both',);

my $btn1 = $frame->Button(
        -text => 'button',
        -command => sub { buttonClicked() },
        -width => 120,
        -height => 40,        
    )->pack(-fill => 'both',);        

$frame->Button(
        -text => 'file selector',
        -command => sub { select_file() },
    )->pack(-fill => 'both',);    
$frame->Button(
        -text => 'exit',
        -command => sub { exit },   
    )->pack(-fill => 'both',);    
        
MainLoop;


sub select_file {
    #...;
    my $file = $mw->getOpenFile(
        -title => 'select file',
        );
    $file = File::Spec->canonpath( $file );
    return $file;
}

sub buttonClicked {
        $mw->messageBox(-message=>"you clicked a button!");
}

Update: it seems to be allready known problem http://groups.google.com/group/comp.lang.perl.tk/browse_thread/thread/d18d09ac8cd1fff6/4262df12756a36bf?#4262df12756a36bf. Wonder if there is still no bug report about it.
