Well, the only idea I have is in the main window controller's
windowDidLoad routine (or whatever equivilent you hav ein your program)
to create a NSThread
that loads the Menu in "the background" (for all practical purposes) ..
There ARE some issues to be resolved.. namely.. what IF the user DOES
try the menu option before
it is loaded.. you may need something like a semaphore that the thread
posts when it has finished loading
the menu items .. and have some menu delegate (or something) check that
semaphore before allowing
the user to select that menu (i.e. keep the menu item disabled until
loaded.. then when the thread has
done loading it.. either it can enable it (a bit risky) or post a
notification that the main thread accepts
and have it enable it.. something along these lines anyway..
Good luck

My application has a drop-down menu whose contents is under user
control, and in some cases may become overpopulated, with, for
instance, 100+ items. Each item may have an icon.
Problem: the first time its title is clicked, it takes several long
seconds before the menu actually drops down. Afterwards, the delay is
much shorter, I guess the bits are bufferized somewhere.
What I would like is to "prefetch" the bits while the application is
initializing. There is a good chance that the user will not click the
menu for minutes after launching the app, so I have plenty of time to
do the job.
Any idea how to do that?
