mobile scroll indicator position

[Mike Kerner]

I have an ios scroller overlaying a text field, but the scroll
indicator/thumb is pretty far to the left of the rect of the scroller and
of the contentRect. The scroller operates to the right of the indicator, so
it's obviously offset left, somehow. What am I missing?

On the third day, God put the animals on hold for a few hours,

And God said, "This is good."
