You need to give Tk the opportunity to deal with updating windows and responding to events. Stick in one or more $MainWindow->Update; inside the various loops. Of course, your MainWindow object may not be named $MainWindow, but you get the idea. You might also want to look into $MainWindow->IdleTasks; which just deals with callsbacks. Both of the above are described in the Tk::Widget POD.

 
perl -e 'print "I love $^X$\"$]!$/"#$&V"+@( NO CARRIER'
