Title: Should disable COMPOSE menu item

When message viewing and tap the Next icon, menu icons (previous, next, delete and replys) disappears for an instant.
Then a compose icon remains, then tap it accidentally.

Note: The "Download complete message" button appears bottom of message and tap the Next icon,
the download button goes down below. It is difficult for me to fix it.
