Just wanted to post it was happening to me too. I have an adblocker, but have the site whitelisted (And I do see the ads). I find the ads actually relevant, and click on them quite a bit. so I had the site whitelisted.
The popup was pretty annoying though, so I added a rule that blocks the popup from showing up. (Cat and mouse, huh? MY ad blocker is now blocking your ads about you not wanting me to block your ads!) Unfortunately that also means the site is no longer white listed. That being said, it's only my work computer thats having the problem for some reason, not my home computer... My home computer / phone is where I do 90% of the sites browsing anyways, And S101 is still whitelisted on them. Just wanted to throw in and say it is happening to me also, not just colorprinthead. (Using chrome by the way).
