Every so often; but over years I've noticed that (in Word) my mouse shows a hell of a sluggish response. So I replace the AA size battery and all is well.
But at other times, it shows the same sluggish response but when I measure the battery voltage, it reads a healthy 1.3 volts. Then, by the time I've measured the voltage and reinstalled the battery, everything is just hunky dory.
Do other people have this behavior from time to me. What's doing on?
