	I think you mean JavaScript, not Java.

	The main JavaScript problem these days is not roll-overs,
	and pop-ups are fairly rare.  The real problem is where
	it is used to create side effects to following a link.

	Almost always, in my view, this can be done in a way that
	degrades gracefully and is functionally indistinguishable to
	a script user, but this is rarely done.

	Most commonly, the link has <a href="javascript:....>.  Sometimes
	it uses onclick, with a functionless href (possibly javascript:,
	again.

	The result, in both cases, is an apparent link that is completely
	dead without javascript.

	I am pretty certain that the desired effect can always be
	achieved by making the actual link a normal href and using
	an onclick action that does what would have been in the
	javascript: URL, then returns false to stop the browser also
	trying to action the href (assuming that this would cause a
	problem).
