PG-cannot prevent full size popup

I want to prevent users from opening the full size popup window and downloading images with a rt-click/save as. Even if I check the "disable rt-click", it seems these options don't apply to the full size popup frame. So I decided to prevent opening the popup altogether. I did the following:

In the PGTheme settings I have UNCHECKED every option that mentions "POPUP". Therefore I was not expecting to see the mouseover for "Full Size" on the images. Yet it is still there, and I have made sure my sub-album settings are not over-riding my defaults. Whenever I view as an unregistered anonymous guest, I still always get the full size popup.

I thought it might be a conflict with group permissions, so I removed the EVERYBODY group right to "view all versions", leaving only "view resized versions" and "view items". That only sort of works, it continues to show the "Full Size" mouseover navigation and still opens the full size popup, except it doesn't display the full size original in the popup; only a broken image icon. But this looks like an error to the user and what I want is to not allow any popups on the full size image.

One other oddity: when I have the popup options unchecked, I dont at first see the mouseover for it like I do with the Previous and Next links. I have to move the mouse over the spot and let it sit a few seconds, maybe back and forth and then I can get it to appear. So its "trying" not to appear, but still does!

Please help if there is a precise combination of theme settings and/or permissions that will acheive viewing all or some versions within the existing frame, but not allowing any popup view. It seems a little buggy but Im hoping I just don't know how to do it.

Much appreciate any answers,
