I notice you have posted same query on at least two other forums.
Is mouse wired or wireless? What is make and model of mouse? What is make and model of pc? What have you already tried? What does Device Manager say about mouse? My crystal ball tells me to ask for more details so that time and effort will not be wasted suggesting things that have already been tried to no effect.
Hi, Thanks to everyone for being concerned on my issue. My problem have been solved. I was just installed wrong driver DVD, so the problem occurs.
Yes "lotvic" you are right. I was posted about the issue on a different forum. Just asking to know, does this prohibited to ask similar issue on different forum? Actually I was on a rush to fix that issue, so I did that.
