Because several commenters here reported problems replying to other comments with reCaptcha, my software guy at Amixa did some checking and found that there appears to be a conflict with nested comments and the google reCaptcha feature. Because of this I have disabled nested comments until the conflict gets fixed.
Commenters can still reply to other comments, but the comments will all be listed in chronological order, which means the replies will not necessarily follow each other. It will therefore be wise that if you reply to a comment, either quote it or provide a link to it in your own comment.
Thanks to all for the help and for participating in the discussion here.
