Hi,
I'm not able to reproduce this at least with the stock Xcode
document-based application template and populating the MyDocument.nib
with several NSPopupButtons. Running leaks with MallocStackLogging
turned on doesn't indicate any NSMenus leaking after opening and
closing documents.

I have run into what appears to be a major leak problem with NSMenus
attached to NSPopupButtons instantiated from nibs.
My app uses several nib files each of which has a window containing a
variable numbers of views (including several instances of
NSPopupButton). Each nib is managed by a window controller and its
window and views are loaded through a call to initWithWindowNibName.
The window is released when the window controller is closed.
ObjectAlloc shows that the window and all its associated objects are
released *except* the NSMenus (and objects that belong to them) that
were attached to the popupbuttons. My code does nothing that I know of
to retain any of these.
This behavior is completely consistent in all nib files that I load
and dispose of this way. I'm using the 10.2 and later nib format, and
compiling and running under 10.3.4, though as far as I can tell the
problem affects all versions of Panther.
Is this a known bug, and does anyone know a way around it? Or is there
something special one is supposed to do to make sure menus are
released? Help appreciated.
