I'm using something like the following Perl/Tk script to get data from a server. Problem is, on clicking the button the Tk window locks up and none of the messages get posted to the display; even the button doesn't get 'released' until after the Telnet session has closed. 
$Btn_1 = $Frame_1 ->Button(-text => "Get details",
     -command => sub{Get_Item_Details ()} );
$Btn_1 ->pack;


sub Get_Item_Details () {

$Label_4 -> configure(-text => "Starting Telnet . . .");
#    Start TELNET dialog;

$Label_4 -> configure(-text => "Sent User Name . . .");
#    User Procedure;

$Label_4 -> configure(-text => "Sent Password . . .");
#    Password Procedure

#    data received is OK . . . et cetera    ;
#close TELNET session ;
}

The Telnet session works great, but the seizure just doesn't look very professional. Any help/suggestions greatly appreciated. Clachair
