Reduced the code down to:
#########################################
use Tkx;
Tkx::package_require("Tktable");
my $b = $mw->new_button(
-text => "Exit",
-command => sub {
$mw->g_destroy;
}
);
$b->g_pack;
Tkx::MainLoop();
#########################################
Still get error on exit;
Comment out this:
#########################################
# Tkx::package_require("Tktable");
#########################################
And errors goes away.
