I'm seeing a new setup now. But the new code doesn't work on my pages. yet... Hopefully its just a short term rollout issue. By doesn't work, I mean it shows blank space. I'd give the url but it's a script I'm working on and don't want it indexed quite yet.
Ok mine are there now. Might just be that way it is now... Just go create an ad and you will see the new way.
I'm getting weird display issues in IE, vertical ads are showing up horizontial and without my colour scheme. Also I had one 728x90 text ads that just displayed "Page cannot be displayed" error. I had to revert back to my old ad setups. It's fine in firefox, I'm not liking this new setup at all.
