How to force security dialog to appear.

Hopefully someone can help me with this. I have a signed applet that runs fine. But if the user, for whatever reason, clicks the 'Decline' button by accident, subsequent reloads of the applet do not allow the user to allow access to my applet. The only way is to close all browser windows and force the current JRE to shutdown. Is there any way to force this dialog to appear every time, if the user hasn't clicked 'Always', the applet is initialized?
