I have a Perl script with a GUI that restarts itself, if I press a button in the GUI. This is done through this simple call in the callback of the button:
exec( $pathToMyself );
This works fine on Windows 7. But on Windows 10, the script ends (and the GUI disappears), but it doesn't restart, unless I go to the command window, which I used to initially call the script, and press the Enter key there.
I don't like this behavior. Can anyone explain, where this comes from or give me a hint, if there's something I can do from the Perl side to restart my script without having to press Enter?
Thanks a lot!

Here's a simple reproducible example:

use Tk;
use strict;

my $pathToMyself = $0;
my $mw = MainWindow->new();
my $bt = $mw->Button(-text=>"Restart", -command=>\&restartMe)->pack();

MainLoop;

sub restartMe {
  print "Restarting $pathToMyself...\n";
    exec( $pathToMyself );
}
