I remember testing 5.x around the 5.3 release (2004) and 6.x shortly after 6.0 (2005), and both em driver versions shipped with these releases were having the same issues. I haven't tested it this year yet, but even in case it's fixed, it's not likely that all improvements will get back-ported to the older branches (over 90% of my servers run something older than 6.x). But as long as fxp works, this is a non-issue for me. Regards, Atanas
