Hi,
If you want to disable the right click option in the browser, include the following lines of code in the header portion of the page.
<SCRIPT>
function noRightClick()
{

if (event.button == 2)
{
alert("Right Click Not Allowed!");
return false;
}

}
document.onmousedown = noRightClick
</SCRIPT>

Regards,
