Ok i searched and didn't find any info on this. Im running iTunes 8 not 8.1 on windows XP and recently it has been running EXTREMELY slow. I have no clue if this is because im not running itunes 8.1 or if it is cuz i have sooo much stuff on itunes. i have a very fast computer and itunes ran fine but then one day it just was being really slow and had lots of lag when you would click something. is there something i should know about itunes 8 or if i should upgrade to 8.1? your help is appreciated Thanks!!!
