The following is rather convoluted but I don't know how to explain my rather odd problem adequately in a simpler way. So I chose this mouse largely because it have the programable buttons, and I programed the two buttons on the side by my thumb to be the command button, so I can therefore open things in a new tab when surfing the wet without having to have a hand on the key board the whole time. Here's where the problem arises. It has the ability to program to keys to the one button. i.e. command and s (with this combo you can quickly save things). I don't want the second button programed, so I left it blank, but now whenever I click the button the whole page I'm viewing gets highlighted for some reason. If I click the link I wanted, it opens in a new tab, no hassle. The the original tab is highlighted blue, and I then have to a regular mouse click to get rid of it. Now I know it's not much to do a regular mouse click, but I shouldn't have to. Also it's distracting having the whole page turn blue every-time. Please help and try to shed light on my problem. Thanks in advance.
