Hi Everyone,
I am comming back to cocoa programming and to this list after a few
years without programming anything, so please forgive me in advance
for any stupid questions. I've read the docs, studied Hillegass's book
again and searched the archives, but still couldn't find a definitive

It sounds like you're trying to debug a "Release" configuration.
Try debugging the "Debug" configuration instead.
Ooops. Doooh! Of course.

Hi everyone,
I've implemented both methods bellow, but my document-based app still

The methods are placed in the window's delegate (MyDocument.m) but
they never get called. Does anybody have an idea why this is happening
Are you sure the window delegate is being set correctly and isn't nil?
Yes.

You can of course check that by logging the address of the object.
