Wait command

[paolo mazza]

Can I disable the mouse while I am listening a speech from the MAC?
I tryed with the wait command, but after the given time the system
accomplish what the user did.
In other words I have a script:

do "say" && quote & field "text1" & quote as AppleScript
wait 100 seconds

If the user click a button during the "waiting time" the system wait fo 100
seconds and then execute the button.
How can I "freeze" the system  during the speech so that nothing happen when
the time has expired even if the user clicked some buttons?
