Q: One day, it could lag while I'm typing a name of a band, the next day it could be fine. The common problems are that the scroll bar moves in chunks, rather then smoothly and it takes a while to search my music for a band. -No viruses. -No programs running. -53GB (out of 100GB) memory (laptop). -Defraged, and CCleaned. What could be the problem?
A: It doesn't seem like a common iTunes problem. My suggestion is to ask your question in one of the iTunes Support forums. All the experts hang there and it's much more likely you'll get a good answer. Hope this helps.
