To prevent Internet Explorer 5.0 or later from displaying a content menu when a user right-clicks in a Web page, add the following to the <BODY> tag:

onContextMenu="return false"

Example:

If your <BODY> tag is:
<font size="1"><b><BODY BGCOLOR="#ffffff" LINK="#8c2118" ALINK="#ff0000" VLINK="#666666" TEXT="#8c2118" marginheight="0" marginwidth="0" leftmargin="0" topmargin="0"></b></font>

alter it to be:

<font size="1"><b><BODY onContextMenu="return false" BGCOLOR="#ffffff" LINK="#8c2118" ALINK="#ff0000" VLINK="#666666" TEXT="#8c2118" marginheight="0" marginwidth="0" leftmargin="0" topmargin="0"></b></font>
NOTE: You should NOT be presented with a context menu when you right click the body of this page.
