Windows Live Mail startup


New Email
1. My Windows 7 WLM always starts up with a full screen New Message window.
With the WLM window underneath it but not visible until you shrink or close the New Message window..
WLM on a friend's W7 does not display the New Message window.
How can I stop it appearing in mine?

2. Also, I can I stop it appearing full screen even when clicking on "New message" on the WLM tool bar?
