Make sure that cpdbf() for all your tables show the same value as cpcurrent(), if not VFP9 will not optimize your queries. This is not a bug, it's a fix. Earlier versions could select wrong data with rushmore if cpdbf() and cpcurrent() did not match. That's why rushmore is disabled in these cases in VFP9.
