Alternative startup for application

Hi, I would like to have an application I am working on to be able to start up in the normal way from the finder, but also have an alternative startup that users can access in some way, where I will display a panel that most users wouldn't normally want to see. Issues I am having with this are

I can't think of a way to do this without iterating over the entire array. It *might* be possible using key-value coding and fancy keypaths and whatnot, but iteration is going to be far simpler to implement and understand. Dave On Apr 2, 2010, at 8:27 AM, David Hoerl wrote: > Objects: > - NSM
