Well, that would be handy, but since all I do is play the game when I play..
Alt+Enter seemed to have no affect on the window.
When I maximize the window, more of the game area shows, but the game itself doesn't resize with the window (does that make sense?) That would work great if the window weren't so small to begin with (thus making the game small as well..)
Here are a couple of pictures.

This is the default window that opens with the game. (The one that opens
every once in a great while..)

This is what it looks like when I maximize (with the game size remaining size as the default window, seen above)
