control will be transfered to

other window ... when installation finished the GUI application will be closed..

code:

os.system("ls -l") & root.destroy

when execute a command "ls -l " and application will be closed

But

os.system("top") & root.destroy

Control will the transferred to the other-window, "top" closed means
application will be closed.. plz..help me..
