Apple's Human Interface Note #6 gives guidelines for the centering of 
dialogs and alerts.  Dialogs and alerts should sometimes be centered on 
the "main" screen (the one containing the menu bar), and sometimes on the 
screen which has the maximum intersection with the frontmost window.

I have a reusable MPW C routine which does this centering according to the 
guidelines.  It's part of my Disinfectant sample source code (module utl, 
routine utl_CenterDlogRect).  Write to me if you'd like a copy.  

Sorry - this has nothing to do with either MacApp or srolling lists in 
dialogs :-)
