When browsing a web page a user has the ability to highlight content on
a page (by holding down the left mouse button and dragging the mouse
over the desired content). Is there a way to disable this option? I
assume there isn't but I have to try.

No, but some people may lead you to believe otherwise. They may also
lead you to believe you can disable the mouse buttons but you can't do
that either.

Your assumption is correct.

Broadly no there is not. IE provides an - onselectstart - event that may
be cancelled, and any browser exposing the selection itself to scripts
should allow that selection to be cleared. Both approached are dependent
on client-side scripting and can be disabled, either individually or by
disabling scripting on the browser. Neither will do anything to prevent
the copying of page content, because there are so many other ways of
doing that anyway, drag selection is just the immediate and obvious
approach.
Cancelling/clearing selections can be useful for other reasons, such as
avoiding undesirable visual artefacts while, for example, animating the
mouse dragging of an arbitrary absolutely positioned page element as
part of GUI.

With javascript, kinda sorta, as others have posted.
But bear in mind that for some of us, disabling script takes one click. For
others, two or three. ;)

In order to prevent people from copying content from your page, you
have to turn the text into a picture (or some other peculiar object)
which is not able to be copied the same was as text. Try to drag and
copy a flash object or a pdf to see what I mean.
But why do you want to prevent people from copying your text? http://www.askblax.com

That doesn't work either. If you want to prevent people from copying
content, don't put it on the web.

Lack of knowledge of the web, and how it works is the #1 answer to that
question, even if people fail to realize it.

Well, you can select text in a pdf :)
Anyway, if people can see the content, they can also copy it, if not in
any other way, then by rewriting it letter by letter (and screen-capturing
images). For reasonable web pages, there are lots of simpler ways, but in
the end, the content is not safe.
But why do you want to prevent people from copying your text?
Indeed.
This is a security question. One should never try to implement
security without first assessing the threat it is supposed to counter.
What is the threat from people copying text - i.e., what losses can it
lead to. Whatever counter-measures once chooses, they should not cost
more than the potential loss.

It works. It is why so many software companies have chosen that route.

The question was how to prevent select, cut and paste and/or
right-clicking to save. Sure, you can save a whole web page, but the
parts that are not text will only be saved as objects (uneditable 9x
out of 10) which is how they were presented on the web.
But why do you want to prevent people from copying your text?
Lack of knowledge of the web, and how it works is the #1 answer to
that question, even if people fail to realize it.
Partially correct.

nothing gained.

Hi,
I would like an opinion on the following:
I have a page which is made up of background-images with transparent
linked images in front of it, which on hover show text in CSS popups.
Due to appropriate alt text, anyone viewing the page with images
turned off, will see the alt text instead, and on hover will see the
popups.
