Hi Jason,

Yes.

I just saved "InternalDataSet.BufferBookmark" in a string and restore it at
the end like that :

function TIBODataset.CompareBookmarks( ABookmark1, ABookmark2: TBookmark ):
Integer;
Var
..
saved : string;
begin
...
if Assigned( ABookmark1 ) and Assigned( ABookmark2 ) then
begin
SetLength( saved, BookmarkSize );
saved := InternalDataset.BufferBookmark;
try
...
finally
InternalDataset.BufferBookmark := saved;
end;
end;

bye,

I don't completely follow what it is you did to make it work. Care to share
it with me?
Are you saying that inside of my CompareBookmarks method that saving and
restoring the internal dataset bookmark resolves the problem?
