I hope someone is on-line that has this problem in their environment.
I would like to know if this routine will resolve the problem:

function TIBODataset.BookmarkValid( ABookmark: TBookmark ): Boolean;
var
BS: string;
ANodeRef: TIB_NodeRef;
begin
Result := false;
if Assigned( ABookmark ) then
begin
Result := true;
SetLength( BS, BookmarkSize );
Move( ABookmark^, BS[1], BookmarkSize );
with InternalDataset do
begin
KeyFields.RowData := BS;
if NodeList.LookupNode( KeyFields.RowBuffer, true, ANodeRef ) then
Result := not (( rfDeleted in ANodeRef.Node.RowFlags ) or
not InternalDataset.NodeList.FilterDel ) and
not (( rfFiltered in ANodeRef.Node.RowFlags ) or
not InternalDataset.NodeList.Filtered );
end;
end;
end;

This is in the IBODataset.pas unit.

Thanks,
