Andy,

You can try something like this:

        [currentModalWindow addChildWindow:newModalWindow 
ordered:NSWindowAbove];
        [NSApp runModalForWindow:newModalWindow];
        // Modal window runs here
        [currentModalWindow removeChildWindow:newModalWindow];
        [newModalWindow orderOut:self];

I've done that before to have a modal window on top of another modal 
window, and it worked fine if I remember correctly.
