I know these are absolutely stupid questions, but someone needs to ask. 
Sometimes the simplest thing gets overlooked because it _is_ so obvious.

Have you checked the little window size button at the top right? Could 
it have gotten accidentally ticked at some point making it full screen?
Have you tried simply grabbing a corner and shrinking it to the size you 
want and see if the setting sticks?

In all the versions since v0.x I have _never_ had Thunderbird open a 
send window in anything other than a small window. Once in a while a 
window that's smaller than I like but that's just a simple stretch and 
the setting usually sticks. Even on the tiny screen of my EeePC it 
doesn't open full screen.
