I think we should stay sensible about this screen copying thing. Lets face it,
copying a large document screen by screen is enough to drive you scatty.
I reckon that small-scale screen copying of some sort should be allowed. For
instance, suppose I download a medical document which I would like to
reference in my bibliography --- in that case I would like to be able to
copy the title and paste it into my bibliographic software. Surely this
cannot be wrong. If all kinds of copying are disabled, we risk angering users
to the point where they start cracking and begin using non-compliant software.
