But point moves when you scroll, so the selected portion of text
changes.  The OP wanted the selection to remain unchanged on both ends
(at least that's my understanding of the report).

"From the _NEW_ point", exactly.  Ergo, the selection changed on one
end.

We have different notions of "the problem".
