Repro from Bug 322973 - "DataGrid: Navigation changes dataset".

Tested on SVN head Win32.

1. Enter the left-hand cell of the very-bottom bottom row -- the
auto-inserted-row one.
2. Click in any other cell
Crash!

With the keyboard
1. (Starts with focus on top-left cell).  Hit Ctrl+DownArrow.
Now at last 'real' row.
2. Hit down arrow.
Now in auto-inserted row (cell value is "(null)")
3. Hit UpArrow
Crash

Same can be seen using the mouse.


Note also the very poor scrolling.
* We never see the very-bottom row.
* Sometimes the active cell of the very-bottom row is drawn over the scrollbar.
* From start, move the horizontal scrollbar bar to the far right, note NO
movement of data.
etc...  Let me know if a new bug is wanted...
