Missing feature in PopUp Pro plugin

I am just disappointed. On your screenshots and description i saw that this plugin does have a function "if user's mouse leaves browser window" – which was the main reason i purchased it. After installation and setup i just saw that function is not part of it anymore!

Please see screenshot of your details


I also attached the screenshot as image:

Please advice ASAP otherwise i would like to request a refund.

Thanks a lot
