Hi Melissa,
Thanks for the name change suggestion.
When I log the test fetch results:

NSLog([[(Owner *)[testFetchResults
OK, point taken - enjoy your trip ;-)
Glad you got it working, and welcome to Cocoa.

Hi,
As I understand it, @property (retain) synthesizes something like this:
- (void)setMyProp:(NSString*)value
{
[value retain];
[_myProp release];
_myProp = value;
}
It is not however clear, and I haven't found it in the guide, whether
it's still my responsibility to call [_myProp

There are varying opinions on how you go about it, but yes, you still

You can't customise the tab view that way (unless you subclass it and
