My wife asked me the other day why she couldn't open a Word document on her iBook. I checked, and found that the entire Office suite had disappeared from her apps folder. Not a trace. Spotlight couldn't find anything Word-related at all. She swears she didn't move anything, and frankly, she wouldn't know how to delete an app anyway, as I haven't told her that bit. Nothing else has changed. Has anyone else had such randomness occur?
