Inspect the "Display At Launch" checkbox for the window in the nib. If
that's set, the window will be immediately ordered in as soon as it's
decoded from the nib, which is obviously not what you want.

If that's what happened, file a bug against Interface Builder. This
trips up _everyone_, experienced and new alike.
