We got a bunch of banners from another agency yesterday that just needed click tags changed to open in "_self". An odd request, but an easy one to fulfill. The font was Arial and they were timeline animations. AS3, which is unusual for a standard banner, but not a problem. However, the revised banners weren't working for the guy upstairs. I thought maybe I had to use "_parent" because of the iFrame, but as it turns out, there's an option in DFA to allow scripts that has to be checked for AS3. So, "_self" worked after all.
Good story, right? I need to learn more about how DFA works.
