Hi guys
i have problem with the garbage collector. May App is a CoreData App
(not document based). If i try to change the database and load a new
one. The grabage collector collects the old NSMangedObjects from the
old store. But this happens in the gabage collector thread. The
topic says it all. i have installed an IKImageBrowser which allows me
to drop images and reorder them. it would be great to be able to
automatically save the dropped images as well as their order so that
the next time the app starts and the image browser loads up everything
is still there.

I will assume that you are using an array controller to handle the
backing data for you IKImageBrowserView. If so, all you will need to
do is archive the array controller's arrangedObjects (or content plus
any filter predicate) and save it to a file - perhaps using NSArray's
