We just transitioned to Flex yesterday and one of the problems we've run into is with HTML ads.
When clicked, they are opening the resulting link right there inside the small 300x250 pixel ad box, instead of opening the link in a new tab/window (which is what happens with all other ad types and for HTML ads on Zen).
I'm being told this is intended behavior and nothing can be done on Town News' side of things.
How are y'all getting around this? We've got a major advertiser pretty upset with us right now. I suggested the workaround of them adding the target="_blank" on their side but of course they balked since they've got the same HTML ad tags running across numerous sites and this isn't a problem anywhere else.
