Does anyone else have this happen? Most of the time, when I open a New Message window in Mail, it opens it right where the last one was, sort of middle-to-right of the screen, where I want it. But every so often (and I can't see any obvious pattern to this) it opens the New Message window way off to the left of my screen.

I'd love to stop it doing that, if only I knew why it did it.
If it's brokenless, don't suffix it...
