Sounds to me like something that may be reported as bug (or at least infelicity) in it.

Yes it is the Linux Ironkey unlocker when I run strace on it I see the execve("program") that is causing the new console.

Then maybe you had best show us your script or (at least) the relevant part spawning a session.

Below is the sub that controls the external program everything else in the program is for controlling the Glade interface. I can provide the rest of the code if needed but I didn't want to muddy up the source of my issues.

sub decrypt_key{
      
    my $Ironkey = '/media/IronKey/linux/ironkey';
    my $Ironkey_pwd = 'Enter your IronKey password: ';
    my $Ironkey_sucess = 'Unlock successful. ';
    my $Ironkey_badpw = 'password not accepted ';
           
     my $data = ($entry->get_text());
    chomp($data);
    $entry->set_text('');
    #sleep(2);
    $exp = Expect->spawn("$Ironkey") or die "Cannot Spawn";
    #$exp->debug(3);
    #$exp->raw_pty(1);
    $exp->exp_internal(1);    
    #$exp->log_stdout(0);
    
    $exp->expect(60, "$Ironkey_pwd");
    $exp->send("$data\r");  #$data comes from the password box of the 
+GUI frontend
    
    ## I tried this way as well
    #$exp->expect(60,
    #    [ qr/password:/ => sub{ $exp = shift;
    #               $exp->send("$data\r\n");
    #               exp_continue;                
    #                   }],
    #     );
    $exp->soft_close();
    #system("nautilus");  Future use
