I'm using a Logitech Mouse on my Acer laptop and when I go to drag a video file to another software program to convert it, the file opens and starts to play before I can drag it. Same when I click the edge of a window it maximizes on just touching it. Like if I want to drag it off screen it maximizes by just touching it on the edge. It's like I have single click enabled and I don't. I can't understand why this mouse is so sensitive. If anyone knows of another setting that would cause this feel free to clue me in. I 'm using Windows 7 HP. x64.
