I have a MS notebook wireless laser mouse 6000, and haven't used it for months; but, my left click button on the touch pad is sticking, so the last two days I have been using it. This blasted magnifier has popped up seven or eight times, the first two
times I lost resumes I was posting online because it confused me... I had no idea. Finally I found this page, and of course, the answer marked "best" is not... as others have pointed out. I then went to "mouse" on the control panel... and there was a button
identified as the "magnifier button... well, I did not see any unusual buttons, left, right, wheel... which is also a button, then after following several of the suggestions here, at my left thumb, in my right hand, there is a small button, right on the edge...
So now I knew what to disable; but, more importantly, what to avoid, and how to undo it... I will keep my thumb off the button, except when I might want/needs it... and that fixes it for me. Thanks for this forum. I appreciate all the suggestions.
