Hi Graham When you change the batteries in a cordless mouse, you often have to reset the wireless connection between the mouse and the receiver unit. On the bottom of my mouse is a very small button, which is flush with the mouse housing which needs to be pressed with a fingernail. The mouse should then reconnect with the computer. Only trouble is that the button is nearly impossible to find by touch alone and sighted help is usually called for. Regards Steve Green -- No virus found in this outgoing message.
