I'm guessing the problem you're having is when you edit a post. When you're writing the post initially, you can see all the posts below it, but the edit function doesn't allow you to see them.
You could always copy and paste the original message into your post, then delete it afterward. When you do delete text that you don't want, do not highlight then hit backspace or delete. Instead, just place your cursor at the end of the text you want to delete and just hit the backspace key. It takes a little longer, but you won't lose your post, which has happened to me many times. I guess I'm a slow learner!
