I don't know if this is normal, but if I am adding many songs, or transfering songs to my Ipod or watching movies or doing some kind of thing where Itunes struggles, it can sometimes freeze my system until I crash it. I almost never have to crash the computer. But it happens daily and weekly with Itunes. Like the program is squishy or not well optimized. But okay.. I have over 25 GB of music. I can understand that its many songs to scroll through for the program. I just wanted to know if Itunes also makes your system hang sometimes too if your using Itunes and perhaps doing some other stuff at the same time...!?
