How to clear script contents after agent hangup

Hi,
In a manual dial mode, when a call is dispositioned customer information is cleared automatically but script content is not cleared. Normally script contents are readonly contents to guide agent, but in my case script contains another dynamic page which is auto updating contents after every 20 seconds. If agent hangup one customer and script screen is still there he can change the contents while I don't want him to do after hangup. Is there any way to clear scripts contents after hangup.
Best regards,
