Seems like there is a bug when clicking the "Write new post", and not being logged in.

You are greeted with a inframe page, and asked to log in. When you log in, the inframe changes to Blog layout, not blog editor as you would expect. Users would have to click the red cross to go back to blog layout, and then click the "Write new post" again.
Hope this can be fixed in future versions.
