I complained about this a couple of months ago, and just downloaded the newest version. Now it seems to work for me. Six things:
1.) My problem could have been all of the WordPress Plugins that I was using, so maybe it worked for others.
2.) I just installed it today, and it seems to work without any problems now.
3.) It doesn't place any error messages below my post like it did before.
4.) It seems to leave your comments section uncluttered until after the viewer post his/her comment, and then a pop-up window opens with a quick game to play. When the game is successfully finished, the comment is allowed to post, and the pop-up window disappears.
5.) Quick, uncluttered, and Fun to use.
6.) I'm wondering if this takes place on a proxy server...not sure. I hope other WordPress users try it out.
