Popup Pro appearing on every page


I am struggling to get the pop-up working as I want it to.

I have added the “Never see this message again” link, but the standard Close button does not have that applied.

It is a special offer on a product so we really want it to appear every time somebody visits the site, on any page, in case they are not interested the first time they visit, but the next day may take a look – so the expiry time is set to 1 day.

The part that isn’t quite working is that on closing the pop-up, visiting another page on the site within the same session sees the pop-up appear on every page – annoying to say the least. What am I missing? I must be able to stop it appearing within the same session multiple times?

Thanks in advance,
