keyboard and mouse

[cakelady]

I have a packard bell cordless keyboard and mouse. The mouse, I have discovered, is dodgy because when I left click it gives the circle thing the scroll wheel gives when clicked. I can get it to work properly by clicking so far to the left of the button that my finger is almost off the mouse. Any way to correct?

secondly, I have a logitech cordless mouse (setpoint 2.49a). I can get the mouse to work, but then the packard bell keyboard doesnt. Do I have to use the two plug in things..will that work OK? or am I just doing something wrong? You will gather I am a tryer, but a bit ignorant.
