When I have two tabs open and use the one on the right it pops open additional tabs everytime I click on the page. Why?
When I use the second tab or open an additional tab to use and I click on that page or the scroll bar a new tab/window opens up with what I'm trying to view, but the page I just opened goes to something else. (99.9% of the time) Do I have some sort of virus? Because I have AVG and it is not showing any issues.
