Recently i have had a problem where pop ups are causing my original tab to become blank. for example: say i was on this page and i click a link that caused a pop up. this page would go blank and my pop-up blocker successfully blocks the pop-up. I noticed it one day when i clicked on a video on the internet (i forget which site). when i clicked play an avertisement pop-up opened causing my video page to go blank. I couldnt watch the video.
