Thanks for your input.
After much testing I have arrived at the following conclusion.
NSTrackingArea when used with NSTrackingActiveWhenFirstResponder or
NSTrackingActiveInKeyWindow may require the mouse to exit and re-enter
the tracking area to activate the tracking. This will occur when the
window resigns and then regains key status. (This appears to be an
obscure bug.) The work around is to release and reinitialize the
tracking area when the window becomes key.
