I've noticed this over the past few days and its taken a little time to realise that only one account out of five that I manage is affected. I can compose a new message using the compose button. The toolbar new message, the file>new, and ⌘N all fail to initiate the new message window.
Hope this is fixed in the next update. I'm using v2.5.8 (#1690) -- You received this message because you are subscribed to the Google Groups "mailplaneapp" group.
