Can't copy/paste URLs. Can't send links/pages. Functions are greyed out. Not

I don’t know when this began, before or after I installed Norton 360 and don’t know for sure that it’s a Norton 360 related problem. I cannot copy URLs in a webpage’s address line (or paste them, too, of course) because the copy and paste dialog selections under “Edit” are grayed out. I also can’t send a webpage or send its link; again, these dialog selections under “File,” “Send” are grayed out, too. It’s a royal pain! Is this possibly due to some sort of security rule enforced by Norton 360 – or is it something else entirely?
