Hi John, thanks for all the great info and pro advice!

For sure... rather frustrating in this one instance.

Definitely. I am glad things are more consistent these days. :D

This is actually the first time in a long time I have had problems with 
this type of thing.

Yeah, good points. I think the only option I found that *might* work is 
using an iFrame shim... but not sure if that technique works on another 
iFrame element (i.e. iFrame shim for menu dropdowns, so they can be atop 
of the adsense iFrame.)

Here are a few links that explain the shim technique (very hackish):

Ah, good idea! This is not for me, so I do not have the Google Adsense 
account, but does Google allow for you to choose the types of ads 
(flash, gif, static, animated...) to be displayed?

Thanks again John, you have been very helpful. :)


My friend has told me that he has other ads that are in same situation, 
but he has control of this iFrame... the iFrame tag has this attribute 


And that seems to make the menu dropdowns display atop of the Flash... 
Hmmm, I wonder if putting the Flash movie inside an iFrame makes it so 
you do not need to apply a wmode? Lol. I may do some testing here... not 
sure which browsers my friend has tested this in.
