Pleased to hear that you've solved your problem and simplified your
scripts.
There's just one thing I have been wondering. Why do you need to keep
track of which nibs are loaded? You wrote in an earlier email "globals
that keep track of whether nibs are loaded, etc." Or, more to the
point, why do you need to keep that information in global variables? As
a rule I simply load all my nibs in the application's "on launched"
handler. There's no great overhead and I know that from then on they
are all loaded.
on launched theObject -- application launched
load nib "abc"
load nib "xyz"
-- etc
end launched
I do want to control the showing or otherwise of windows, so I'll
uncheck the "Visible at launch time" check box in Interface Builder for
all my windows, and then use "show window ..." and "close window ..."
as and when needed. You obviously have to load a nib containing a
window before you try to "show" the window. If you load all your nibs
right at the start when the application launches then you don't have to
worry about that - everything's loaded. I can't, on the face of it,
think of a reason for not loading the nibs up front. But if there is
one, instead of keeping track of which at any particular time are
loaded, how about simply trapping for it? Say you have a window in a
nib and you want to be sure that the nib is loaded before you show the
window, these lines would trap for it (in other words, the single line
"if not ..." before the line "show window"):
if not (exists window "nameOfWindow") then load nib "nameOfNib"
show window "nameOfWindow"
Obviously I don't know your application, so there may well be a good
reason why you need to keep track of the loaded nibs. And this is only
a minor point. The major issue, that of simplifying your code, you have
clearly solved. Your point about cutting dependency on global variables
is a good one. I am sure that as a result you will find that your code
is much easier to manage/update/build on etc.

Whoo hoo!
SOLVED!
Thanks to all, I'm back on track after three grueling weeks of
confusion. I
moved all my "global to the application" variables back into the main
script, and am using that script as the sole controller, keeping track
of
"nib loaded" booleans, etc, Then I pass whatever I need to pass to
subscripts via handler parameters, and use user defaults as often as I
can.
The added bonus is that I have drastically cut my dependency on global
variables, and have been able to replace many globals and properties
with
local variables, this freeing up memory and making my code simpler.
Thanks to Christopher Hickman, Jasper Van Proeyen, Philip Buckley,
Matthew
Stuckwisch, Mark Butcher, and anyone else I'm forgetting... I'll put a
"special thanks" for you in the Read Me of my app!
Thanks again,
Graham Jones.
