Dear friends, I've winXP PRO SP2 , last month i bought "SUPERCOMP" optical mouse which has 800 dpi resolutiuon. Now my mouse is working too fast, whenever i click once on any icon it automatically clicked twice-thrice. For example, when i click once on NEW TAB under opera/firefox/ie7 then sometime it opens 2-3 Tabs instead of one. When i click on [X] close button of any opened windows then automatically also closed other windows which is just behind that window. After this problem i reduced sample rate to 80 and disabled fast intialization under mouse setting. But still i've problem. Its PS/2. Can anyone tell me whats the problem? And how can i solve it??
