Esteemed monks,

It was time to add some colour choices to various things in my monster Perl/Tk application. So I added a simple little method using chooseColor, but alas it was a dismal failure. Oh, I could choose a colour alright, but alas, if you wanted to close the colour picker window ir click on the 'Cancel' button, it crashes the application.

Here is a minimal test case that I can make crash on my machine.

use strict;
use warnings;

use Tk;

my $cfg;
my $font_colour;
my $wd = MainWindow->new();

$wd->Label(
  -text    => 'Color',
  -justify => 'right',
  )->grid(
  -column => 0,
  -row    => 4,
  -pady   => 20,
  -padx   => 20,
  -sticky => 'e'
  );
my $colour_button = $wd->Button(
  -width   => 6,
  -command => sub { $font_colour = colour_picker() },
  )->grid(
  -column => 2,
  -row    => 4,
  -pady   => 20,
  -padx   => 20,
  -sticky => 'e'
  );

if ($font_colour) {
  $colour_button->configure( -background => $font_colour, -activebackg
+round => $font_colour );
}

MainLoop;

sub colour_picker {

  my $colour = $wd->chooseColor( -title => 'Color Picker', -initialcol
+or => '#000000' );
  print "Colour chosen: " . $colour . "\n" if $colour;
  $colour_button->configure( -background => $colour, -activebackground
+ => $colour );
  return $colour;

}

In the event viewer the error is always: 
Faulting application perl.exe, version 5.8.8.820, faulting module msvc
+rt.dll, version 7.0.2600.2180, fault address 0x000378c0.

I am using Perl 5.8.8.820 Activestate build, Windows XP-SP2.

I am not knowledgable enough to know how to troubleshoot this any further myself, so any assistance would be appreciated.
