jdtoronto has asked for the wisdom of the Perl Monks concerning the following question:

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.
