HELP--removing PUBLIC from one user

Oracle has a dozen or so tables with PUBLIC access (e.g. public.form_blk, public.form_page, etc.) I want to block the access of these tables to one user but keep the PUBLIC access to all other users.

I don't want to have to go thru all of these tables dropping the public access and re-granting the access to all but this user.

Any suggestions?

(Why am I doing this? Because PowerBuilder displays all of these tables when a data window is created and it's getting to be a pain when I am building a lot of new data windows.)
