Has anyone seen a set of adwords that when clicked the link opens in a new window?

Im sick of the add stealing my customers who are half way through buying from me, I want it so that if they like the sound of the link

wait a minute , you want GOOGLE Ad-sense to open in a new window .( i think this is against its rules and GOOGLE policy ) and may cause to close your account .

No you can't.

Google Adsense says, that's the way advertisers want it, and they pay for it to us and publishers!

I know its annoying, but probably Google will do something about it soon...at least for big publishers
