tracking area problems on 10.4.11

Hi,
I'm trying to get the following events to trigger:

- (void)mouseEntered:(NSEvent *)theEvent
- (void)mouseExited:(NSEvent *)theEvent

I'm using this call to get it to work:

[[mWindow contentView] addTrackingRect:[mWindow frame]
                           owner:[mWindow contentView]
                           userData:nil
                           assumeInside:NO];

I've also tried:
[[mWindow contentView] addTrackingRect:[mWindow frame]
                           owner:mWindow
                           userData:nil
                           assumeInside:NO];

mWindow is a custom NSWindow and the content view attached is also a
custom NSView.  I've defined the above event handlers in both custom
classes and set breakpoints, print messages, etc. but despite who I
set as owner of the tracking rect, I can't get the events to trigger.
Is there something else I have to do?

thanks,
wes
