If you have trouble with iTunes 9.1 using by list mode w/ column browser,
would be this solution so helpful !

at first, Hit (cmd)+B , then change “List Mode”
and if you using Cinch & Zooom, please shutdown. (also any other concerned with “mouse gesture” application)

then no more crashes, will be completely solved the terrible prob.
I seems like this prob is an interaction with other 3rd party software. (not iTunes)
