iTunes 10.5 processor hog and wont run iTunes Store
Had one of those head screws the last few days with this one.
As soon as i run iTunes on my customers laptop with 4 GB ram and a dual core processor the system slows almost to a halt. I’ve looked at everything. I’ve uninstalled iTunes and re-installed it three or four times, tried updating the system with Sony updates and windows updates and all the other things that i could think of.
