Hi......My mouse seems to have a mind of its own these days....When I go to Control Panel, Mouse, it tells me that it is working properly....But my mouse doesn't move where I want it to go sometimes.....Other times, it finds its way to the taskbar & I get a drop down box.....It's as if I did a right click on my taskbar or system tray......The only way to get rid of the drop down box is clicking on Properties, then Cancel.....Sometimes, when my mouse acts up, it disappears off the screen from one spot, and appears clean across the screen in another spot too.......What should I do ?
