Q: I am using an Ativa optical mouse. Is it an electronics problem or is there something else going on?
A: It is the problem with the mouse. If it is the ball type (turn it upside down, see a ball there?), then remove the trap door, clean the two wheels inside the mouse that the ball is in contact with and you are good to go. Use a safety pin or a papaer clip. If it is electronic type, and if it has a wheel in the centre, it sticks. Get another mouse. Don't try to repair it - mouse is so cheap nowadays, it is not worth the trouble. If that is not the problem (wheel), then your mouse pad is the problem. Just use the mouse on the table top (if it is glass table top it won't work) and it will be OK. Bottom line? There is a problem with your mouse. That's your first stop to diagnose this problem. No, you do not have a virus. Virus does not behave that way.
