No... I'm talking about when you click certain link that open pop-ups, ads aren't blocked on them. Refreshing the pop-up blocks the ads. Chrome doesn't have this issue, I've tested it. Opera has this problem with both adblockers available (ABP and Adblock) that's why I'm guessing that it's an Opera specific issue. Apparently Opera does something in a different way than Chrome, in this case.

just open a radio station. It opens in a pop-up window with ads, refreshing blocks them.
Same thing happened the other day when clicking the "watch on Youtube" button on an embedded video. The youtube page had ads, and needed a refresh to block them.
