I'm doing this to prevent an InvalidateBookmark on a record that is
not displayed on the users screen for multi-user synchonization.

Basically user b made a change to the same table that user a has open
but user a might not have the record that user b changed even on his
screen so I don't need to even bother to do an InvalidateBookmark on
that record from user b.

The actually implementation get's complicated. Basically I have a
variation of the IB_SyncCursor that is available in IBO but I've
written my own to work exactly the way I need. Right now I'm doing
an InvalidateBookmark on any record changed by user b even if that
record is not even on user a's screen. I would like to prevent
this. A side effect of doing an InvalidateBookmark when it is not
needed is that you loose changes for any records that are currently
in dsEdit mode.

Hope this helps explain what I'm trying to do.
