While I am browsing this forum, I am suddenly starting to get new screens for different websites such as Target.com and Netflix, which are companies that do pop-ups, but I've never seen full-screen ones. This happens automatically - suddenly my HTF screen is completely eclipsed by the screen of another site altogether, and I have to click on the X at top right to get rid of the screen. HFT is still there underneath, and is in my tray at the bottom, but this is really annoying - it's like getting gigantic pop-ups that obliterate what I was viewing entirely. Has anyone else run into this? What might be the cause? It doesn't seem to happen to me at other sites.
