Actually, that is a very good idea. In fact, it would be VERY helpful if you could provide a "window" of use of the program both with and without the password. In other words, the presentation is provided to a customer using a timed expiration. For example you give them the presentation on June 1st and you set it to expire on June 30th, 2003. At that point, just like you stated, The password feature would kick in on July 1st, 2003. But if the programming could be done, you could also set the password feature to work PRIOR to June 1st. Is this possible?
