My windows don't cascade

I have an NSDocument-based application that is still pretty close to the
Xcode template for "Cocoa Document-based application"; i.e. I subclass
NSDocument but not NSWindowController, and I implement -windowNibName
but not -makeWindowControllers.

When I open a new document, it doesn't cascade; it opens with the same
frame as the previous one.

Setting a breakpoint at -[NSWindow cascadeTopLeftFromPoint:] shows that
it is indeed called, from this stack:

  #0  0x94f5d6a4 in -[NSWindow cascadeTopLeftFromPoint:] ()
  #1  0x94f415e6 in -[NSWindowController _windowDidLoad] ()
  #2  0x94edf476 in -[NSWindowController window] ()
  #3  0x94edf376 in -[NSWindowController showWindow:] ()
  #4  0x94edf2b9 in -[NSDocument showWindows] ()
  #5  0x94edd580 in -[NSDocumentController openUntitledDocumentAndDisplay:error:] ()

however, the argument to cascadeTopLeftFromPoint appears to be always
(0,0).  Any idea what could cause this?

Thanks,
  Stefan
