Dani,
What you are seeing here is what sometimes happens after I tap the 'Send' button. The page semi refreshes as if it is processing my post and then appears as you see it there, as if it's still in edit mode but without the 'Send' button. What I have to do next is select and copy everything I've written, refresh the page, paste my comment back in, and then click the 'Send' button again. It always posts okay on the second attempt.
