OK, I am new to PERL\TK and I am writing a program that will prescreen and wipe out spams from my email box before bothering to download them. I would like to have a window update during the loop so I can gage progress. It seems that the information buffers until the lop is over and then updates. Got any suggestions? The below would check the connection status. it too seems to buffer and then post after the sub completes. 
# Check Connection
sub connectInfo{
    infoCheck();
    #getCfgInfo();

    $TA -> delete("0.0", "end");
    #settings();
    
    $SA -> configure( -text => '');
    $SA -> configure( -text => 'Configuration Retrived');

    use Net::POP3;

    my $res = my $pop = Net::POP3->new($popServ, Debug => 1, Timeout =
+> 60) or die "Can't Connect: $!\n";
    $TA -> insert('end', "Server Available   : $popServ\n", reset) if 
+($res);
    
    $SA -> configure( -text => 'Server Check');
    $res = "";

    $res = $pop->user($popUser); # or die "Can't Authenticate User: $!
+\n";;
    $TA -> insert('end', "User Logged On     : Successful\n", reset)  
+   if     ($res == 1);
    $TA -> insert('end', "User Logged On     : NOT successful\n", rese
+t) unless ($res == 1);
    
    $SA -> configure( -text => 'User Check');
    $res = "";

    $res = $pop->pass($popPass); # or die "Can't Authenticate Pass: $!
+\n";;
    if ($res > 0) {
        $TA -> insert('end', "Password Author.   : Successful\nServer 
+Responding  : $res Messages Waiting\n") ;
    } else {
        $TA -> insert('end', "Password Author.   : NOT successful ($re
+s)\n");
    }
    
    $SA -> configure( -text => 'Password Check');
    $res = "";

    $res = $pop->quit();
    $TA -> insert('end', "Log Off Server     : Clean Logoff\n\n")     
+if ($res == 1);
    $TA -> insert('end', "Log Off Server     : Broke Connection\n\n") 
+unless ($res == 1);

    $TA -> insert('end', "System Ready\n\n");
    $SA -> configure( -text => 'Log off');
}
