Silly Problem

[David C.]

Hey folks,
I know that I can center my application stack like this:

set the loc of me to the screenLoc

...but what's the proper way of centering a sub stack (about box,
preference stack, etc) to the position of my main stack, wherever it
may be on the screen? I'm pretty sure I've been down this path before
but the answer, however simple it may be, somehow eludes me.


Best regards,
David C.
