In continuation of implementing 3rd party adserving with Headlight we did some testing with Flash banners. We found out that a lot of companies when launching a link in a flash banner are using onPress method with getURL. This is not supported in IE6/7 nor Firefox - so don’t do it like that!

What you need to do is to use the (industry standard) onRelease method instead of the onPress method - as advised by Adobe here and here.
