I would advise against it to be honest. If it's to protect images it won't do that anyway , there are ways rounds that especially with IE6 otherwise it it intensely irritating if like me you like to open links with a sepearate window as I do here on the PCA forum.
I've seen a a couple of these no-right-click scripts - so far not one has worked on Opera and this one didn't work on Mozilla either - I right clicked and got the usual right-click menu. It worked on IE and an ancient version of Netscape.
