Are you saying I should not be posting anything which is not "for 2.0" until it is released?

It never makes any difference for me whether next release is coming out or not... > Cheers, > Andreas > >>> The characters at the end tell what handler (read/write, oea/uea) is >>> defined for SPR. > -- Alexey
