Nadya,
the solution it is simple.

VFP uses RECNO()/RECCOUNT() when compute the scrollbar gap.

When a index is active, it uses the index keyPos/keysCount.

Then active a filtered index with FOR NOT DELETED() condition
( on VFP9 this optimize se SET DELETED ON filter also )
* on a cursor with none indexes, active this ( or faster idx )
INDEX ON .T. FOR NOT DELETED() TAG TDEL
