As for NSTrackingInVisibleRect: I'm a bit mystified by its utility. I had though that what I was achieving by including this option was that the tracking area would not be triggered for parts of the rect that were visually occluded. However, it seems to function in quite a different way.


It's a shortcut for a common case: when you want a tracking area on an entire subview. Specifying this option allows you to set up the tracking area once, and never have to worry about updating it.
