Also, I’m not sure that that problem describes the experiences that we were having. As soon as the users installed EndNote X and used it in her Word 2007 file, Word would freeze and ultimately crash. One user noticed that the problem went away after she uninstalled EndNote X (because the problem, for her started as soon as she installed EndNote). Once she reinstalled it, she noticed the problem again so we researched it online and found users who advised us not to use Instant Formatting with Track Changes. Once we adopted that practice, the problem went away.
