I just installed Adblock after trying to get an answer from MS as to how to stop those “mouseover” popups from happening. Other than disabling scripting, they didn’t have an answer. More and more frequently, those mouseover popups are ads.
Adblock stops them.
Incidentally, I had firefox on the computer for a couple of days, and it did the same thing. Looks like advertizers have found a new “feature” to exploit. and Adblock has found a new solution.
Now, if FR weren’t so slow, I wouldn’t have double-posted.
