Try using your 'Right Mouse Button' on this Page
The code used to make this work is shown below (Cut and Paste between the HEAD tags of your web page):
| <script LANGUAGE="JavaScript"> <!-- function click() { if (event.button==2) { alert('You Can NOT use the Right Mouse Button on this Page, Sorry!'); } } document.onmousedown=click // --> </script> |
(If you change the 'event.button' value to 1 you can stop the left mouse button working!)
