Quick help for the problem of never seeing "case 1":
you need to tell the program to redraw the widget.
One way (possibly not the best, but it works):
sub change {
$LB->configure(-text=>'case 1');
$LB->update;
sleep 3;
$LB->configure(-text=>'case 2');
}
As for the problem of doing a longer job in the
background while the GUI continues smoothly, I
guess you'll have to programm a multitask/multiprocess
script. How you do that depends on what exactly you
want to do in the background job.
Have fun ...
