Hello....I have a new Microsoft Wireless Optical Special Edition Mouse and it occassionally fails to move the cursor. The cursor "stalls" and does not follow the mouse movement intermittently. The mouse transmitter is connected via PS/2 and it is located by "line of sight" very close to the mouse. Ive uninstalled and reinstalled the software but the intermittent tracking problem persists. I use MS Win XP Pro. I am surprised that this Microsoft hardware product does not work well with a Microsoft mouse. Is there anything I can do to "cure" this problem? Thank you.
