I am a long time Mac user (since 1994/System 7.5) who just upgraded to OS X Lion. I've noticed that when I move part of a window off screen and then move it back on-screen, it has been automatically resized (i.e. shrunk) according to how much remained on-screen. I don't want it to do that. I want it to be the same size when I move it back as it was before I moved it, so how do I fix this?
