I am having problems with Perl/Tk windows. Certain ones have the feature that if you obscure them with another window - wholly or partially - then reveal them again, the window contents are missing - wholly or partially again. I have found this with both mySplashScreen and Message windows. How can I avoid this happening, or is this a "feature" of these objects? Sample code I have been using: 
use Tk;
require Tk::mySplashScreen;

use strict;
use warnings;
 
my $s = mySplashScreen -> new
(
    -image => '',
    -text => 'testing, one, two, three...'
);
for my $n (1 .. 10)
{
    print "$n\n";
    sleep 1;
}
$s -> destroy;

And: 
use Tk;

use strict;
use warnings;

my $mw = MainWindow -> new;
my $m = $mw -> Message (-text => "testing, one, two, three...") -> pac
+k;
$m -> update;
for my $n (1 .. 10)
{
    print "$n\n";
    sleep 1;
}
$m -> destroy;
print "Done\n";

If this feature is unavoidable for these objects, is there an alternative type I can use? All I am trying to do is display a message window that remains on the screen while a called application (a scanner program) runs. I cannot believe how difficult it is to achieve something so basic. I have tried Google and turned up nothing for this.
