That will eliminate virtually everything, they have an Exceptions section, but I don't want ANY, so I have never looked into that.

At the moment, I can think of only one site that I'd like to have the popups, the University of Colorado Athletic site. That is a new development for them, so I may have to reconsider. I'll have to either stop going there or figure out the Exceptions section.

There are a few sites I use that have enlarged pictures as popups, The Seattle Times is an example. I have no problem with these working, I suppose because I am initiating the operation.
