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
