For whatever reason, a couple of days ago my right-click options on the mouse stopped working when I am online. Specifically, I can highlight something but when I right-click to copy the little window that opens giving me those options does not appear. If I am off-line, it works just fine. Any ideas as to what I can look for?

Here's a copy of my latest Advanced System Care scan log, if that helps anything.
