Since Thunderbird was last updated on the 5th August, the page to compose a new email, no longer has a "send" or "attach" tab. I cannot now send any emails through Thunderbird. I have requested technical support twice, however, the only response has been an automated message saying someone will get back to me. That has not happened. I am only able to send any emails via our internet provider's website, which is Slingshot.co.nz.
