FindIndex question

[Mike Kerner]

just to sanitycheck myself, i opened 9.6.9, created a new stack, and added
a dg to it.
then i fired up the pb. expand the card, and you'll see the dg. there are
two behaviors assigned to the dg. the first is button id 1005 of stack
"revDataGridLibrary" which has, as its behavior, stack
"RevDataGridLibraryBehaviorsDataGridButtonBehavior"

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
