User blog:Samlovesham/Annoying times when trying to post comments

I don't know how many other people have been experiencing these problems, or if it's just a problem with my computer or something, but recently when I've tried to post comments SOMETHING goes wrong. A lot of times it posts it twice even when I only hit 'post comment' once. Other times my comment just DOESN'T SHOW UP, no matter how many times I refresh the page, exit out and go back, or log out and log back in. Have these problems happened with anyone else, and does anyone know how to fix this?
