that doesn't surprise me... thank you for your help.

hooray, I think this was a crucial piece of info I was looking for!

more about what I was trying to do:

I have a login window which validates name & password and if successful
opens another window.  This window2 has two views which are loaded into
it from separate nib files.  (the reason for this is that each view is
getting something from a db, and will be reused on yet other
windows--my idea was to write the views and their controllers,
including db queries etc, once to avoid putting that code in many
different places).  Two problems I've run into so far, which might be
related, at very least through my ignorance of how these windows are
working:

--when loading the views into window2, I'd like to use an instance
variable from Window2controller as a parameter in my db query to
display information in the view.  Currently the views are getting
loaded in Window2Controller's -windowDidLoad method, and when the view
initiation goes to try to get a variable from Window2Controller, the
var is always null.  Am I correct in thinking that if I move the view
loading to Window2Controller's -awakeFromNib I'll be able to get a real
live variable value?

--I want the login name and password to be available throughout the
program.  I thought that if the login window had a controller, I should
be able to set the name and password as variables in
LoginWindowController and then access them by calls such as

[[LoginWindowController sharedLoginWindowController] name];

assuming the proper methods exist.  So far no luck-- the vars come back
null.  At first I thought this was because I did a [window close] on
the login window, but then I switched that to an -orderOut and it's
still not doing what I intend....

thanks for all the suggestions I've gotten so far, any further help
much appreciated.  Happy New Year everyone
