Did you remember to enable mouseMoved events? By default AppKit
doesn't send them because they are so numerous; you have to explicitly
ask for them.

I don't think you have to enable mouse events when using an
NSTrackingArea. At least, right now I don't have mouse events enabled
on the window in question, but mouseMoved does fire appropriately. As
a test I did enable mouse events and the problem did change, so it
appears that tracking areas don't require setAcceptsMousedMovedEvents.
The problem I am having is that the toolTips don't update properly, as
long as I'm inside the tracking area the toolTip won't dimiss. I'm
also wondering if my implementation could be better...
