Because vapps may have changed which will add and/or remove buttons. The buttons are disabled as soon as the user clicks them. This is because some of the apps they launch have a lag time of maybe 60 seconds or so before they appear. We found that if we don't disable the button, the users click repeatedly (starting the app maybe 20 times) before they see the app start. The timer re-enables the button after a pause of about 90 seconds. So as far as I can tell, I need a timer for each button.
