Thanks again.
It seems tracking area is not suited for this application. And I
revert to cursor rect finally. Wish a better tracking area from Apple.

Thanks. I've tried NSTrackingArea, and it seems a clearer concept and
easier to use. However, there are still two problems I can't fix:
1. Setting cursor in initWithFrame: and awakeFromNib does not have
effect. So I can't set the initial cursor.
2. Setting

Cursor-tracking glitches, where the cursor doesn't revert when
exiting a view, are really common in Cocoa apps. I see them in all
kinds of apps, even major Apple ones like Mail and Xcode. I think
it's due to bugs in AppKit, unfortunately. These bugs have been
around since at least 10.0, but
