>rowsource: myalias.itemname, itemno, itemcode
>columncount: 3

>(in DE there is an opened freetable, containing the previous fields and other 5 more. Reccount: 6000)
>If the order is set to nothing, the list works fine.
>But if I set the order to any index tag, the list behaves strange.
>I mean, that pushing down the left mouse button over the fastscroll square, (which also indicates the position in the list - sorry but I don't know the official name of this) the list items scrolled 50-100 items down. If I release the mouse button the list step back to
>the original position. It is frustrating, because if I not only push and release the button, but scroll with it, after stopping and releasing the mouse button, the list steps forward 50-100 items, instead the place, where I wanted to stop.
