Building and running it on Snow Leopard causes it to crash horribly.
Try reopening/resaving your nib in the latest Interface Builder?
Thanks. I did try that, but it didn't help.
I tried using this .xib file in a simple test application, created the
view controller, sent it the loadView message...it worked.
I have also tried starting with a fresh .xib file, created with the
newest IB, and it will crash while trying to load the view.
Clearly, I am doing something bad, which Leopard is tolerant of, but
Snow Leopard isn't - What that is, I am not sure.
Here is a more complete stack trace:

Basically, what happens is that the window controller that is managing
the palette is asked if it is visible:
[[aController window] isVisible]
Since it hasn't been loaded yet, Cocoa loads the window and sends the
controller the awakeFromNib message.
The view on the window has it's own controller. awakeFromNib needs
access to the view, which causes the view controller to load it.
The moment it tries, the application crashes in Snow Leopard, but not
Leopard.
