[MlMt] Share -> Send Message fails

[Randall Gellens]

MailMate 58999 on MacOS 11.6.5.

Using the "share" function from Safari or Firerfox to send the current 
page via MailMate now drops all data. It used to create a draft message 
with the "Subject:" header field pre-filled with the page title and the 
body pre-filled with the URL. Now, it's all blank.
