As far as I understood, the cursor stability fix was about changes made by the statement to its own data (eg an UPDATE or DELETE). The text I quoted defines significant changes as "if and only if it is independent of CR, and, had it been committed before CR was opened, would have caused the sequence of rows in the result set descriptor of CR to be different in any respect" Mark -- Mark Rotteveel ------------------------------------------------------------------------------ Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
