Thanks very much for your offer, but I've tried your method and, though it DOES work, it does not copy the added graphics tables (as on page 6, 7 and many more). And I need those too.
I appreciate your effort though.

I can't believe there's nobody here who knows enough of this stupid program to tell me how to perform a simple (or at least I think it should be simple - wouldn't be a problem in powerpoint or word for that matter, but this program is in no way intuitive) operation like removing a background.

Any help is greatly appreciated!
