I've tried responding to many of your post and it wont go through. I was having the same problem on my blog and learned that it is due to the response setting style. (I had googled the issue.) I guess it is an issue that blogger has been having. You need to change your response setting so that it is in a pop up box or the such, anything other than the in text mode.
