I just performed the following test and the dgRectOfIndex[1] returned  
the proper result.

1) Created new Data Grid.
2) Changed style to "form"
3) Turned off fixed row height
4) Turned on "cache controls"
5) Turned off "persistent data"
6) Positioned Data Grid at 0,0

I then added about 50 or so lines to the Data Grid. Here are results:

put the dgRectOfIndex[1] of group 1
0,0,233,21

I then scrolled to the bottom of the Data Grid:

put the dgRectOfIndex[1] of group 1
0,-451,233,-430

I then tried scrolling the first index back into view and it worked:

dispatch "ScrollRectIntoView" to group 1 with the dgRectOfIndex[1] of  
group 1

Just let me know what steps you are taking and what you are seeing. If  
there is a bug that is the only way I can track it down.
