cascading windows in document architecture

I have a small, relatively simple document based application that I 
created using Xcode 2.4 and Interface Builder 2.5.4 on a Mac running 
Tiger.  Recently, I moved it to my new iMac running Leopard.  On the 
old Mac, document windows cascade, just as expect, but on my new Mac 
running Leopard and Xcode 3.0 and Interface Builder 3.0, the document 
windows no longer cascade.

Apple's "Window Programming Guide for Cocoa" says " If you use the 
Cocoa document architecture, you can use the NSWindowController 
setShouldCascadeWindows: method to set whether the window, when it is 
displayed, should cascade in relation to other document windows (that 
is, have a slightly offset location so that the title bars of 
previously displayed windows are still visible). The default is true, 
so typically you have no additional work to perform."  This seems no 
longer to be the case.

I'm reasonably certain that I've not changed anything that would 
account for the difference (famous last words that I'm prepared to 
eat, if necessary).  Has anyone else noticed this behavior?  Is there 
a setting that I've missed/a fix that I can apply?
