Pop Over Disregards Conditions?

Love the concept for this plugin if I could get it to work for me.

I have a pop set to suppress on certain post types and only show on posts yet it appears on all pages and posts.

If you click on the X which is set to stop showing it forever it still re-pops again on the next page clicked.

Expiry was set to 60 days.

I have turned it off on my site because it is clearly annoying the hell out of visitors although I would really like to be able to use it and have it work effectively.

I am using wp-super cache with this site... are there any issues with using super cache with this plugin?

Thanks
Chris
