TDBGridScr is like TDBGrid, but vertical scrollbar does not have only 3 states (and not only for non-filtered Paradox files as in Delphi 3,4). Scroll box of scrollbar (thumb) shows position in dataset and scrollbar of 32 bit version behaves like in other applications - size of scroll box changes showing relation of visible data to total number of records. By dragging thumb changes position in dataset (while dragging, not after end of dragging as in Delphi 3,4).
