To disable clipboard warning in ie7

In you’re using Internet Explorer 7, there are several enhanced and tighten security features
that have been incorporated into IE7. One of them been restricted Clipboard data access by 
websites and web pages. In Internet Explorer 7, both IE 7 installed on Windows XP or IE7 that 
comes together with Windows Vista, the behaviour occurs when you visit a website or webpage 
that tries to access the information stored in Clipboard’s memory, as Clipboard’s memory 
stored data can be sensitive and private. For security purpose, IE7 will pop-up a warning 
alert message as below:


1.Go to Tools -> Internet Options.
2.Go to Security tab.
3.Select “Internet” zone, then click on “Custom level…” button.
4.Scroll down to “Scripting” section (at the bottom few).
5.Under “Allow Programmatic clipboard access” option, check or select (tick) Enable. 
  Default action for this option is Prompt, which cause the pop-up message whenever there 
  is any attempt to access the Clipboard.
6.Click Ok twice to exit from Internet Options.

Changing the preference to Enable for “Allow Programmatic clipboard access” option can 
increase security risk. You can set it to Disable to disallow all website’s access to 
Clipboard’s resident data. However, the better and more secure alternative is to edit 
the “Allow Programmatic clipboard access” setting for “Trusted sites” 
zone (steps same as above, only that you select “Trusted sites” in step 3 instead of “Internet”), 
and add the websites that you trusted and selected into Trusted sites zone.
