IPlural: Sorry, I had to go to work....... thanks for the links, I understand now. I think I will leave the mouse in the P/S2 port for now, as there is no discernible difference that I can see. I'm just happy to get rid of that damn 2 button mouse, it felt like I had one of my arms removed! Aaaaahh.....4 buttons and a wheel.... Heaven!!
Thanks to everyone who put forward suggestions.....I can always rely on you guys to sort me out!
