Yesterday I got my computer back from the shop. It's only the second time in 15 years I've had to take it in. IC did a real number on my system--inserted things into folders, showed hidden folders, basically rendered my computer unusable with a constantly reappearing warning message that not only wouldn't go away but kept me from using anything else on the computer. The tech who fixed it said it is a very common complaint with this software. I read the warnings pre-download but hoped my experience would be different. I actually had a good experience for almost a year. I don't know of another software package with the kinds of features IC had. As I said, it worked pretty well. Coincidentally(?), I downloaded iTunes 7.7 before the problems began and lots-o-people had problems with that version of iTunes.
