Problem with NSTrackingArea

I'm using tracking areas in a view which work fine until I resize my 
window and the view.  After removing the old tracking areas and adding 
new ones, the new ones are stuck as "pendingInstall notInstalled 
disabled".  From then on any tracking areas I add don't work because 
they're still stuck as pendingInstall.  Is there some update method 
I'm supposed to call or a notification I need to post to get the 
tacking areas to finalize their install?
