Yup, well said some people will never convert.
I just need to disable right click on just one page, not the entire site. But still you are right, it can be annoying to disable right click.
There's actually a small snippet of code that swallows any possible Javascript error messages in production environment.
I saw it here:
HotScripts.com :: JavaScript :: Miscellaneous :: To hide the errors , it was written by a French person, but that script is no longer there.
But that code comes in very handy whenever there are errors in external Javascript being used on one's site.
Very rarely and under some rare circumstances the StatCounter javascript was giving me errors, and also Google AdSense - under those circumstances the universal error handler came in very handy.
