Forget what I said.
If the value takes effect, window isn't nil.
The trick is to uncheck "show window on launch". If I chekc that box, my window is visible at first too.

>> I am trying to set NSWindow (borderless, with no controls) to be transparent before I display it (so that I can fade it onto the screen). Unfortunately, I don't seem to be able to - it loads, visibly, then sets the opacity to 0 (resulting in the window flickering at full opacity, before disappearing and then fading into view. Sure, it's a fast flick - but it's ugly, and not the effect that I'm looking for. Does anyone have any idea how to set opacity to 0 before displaying the window?

To justify my actions, this is because the app loads into the menu bar, not the dock, and so (in testing) I discovered that users thought it hadn't loaded at all. So, on first load only (unless specifically requested otherwise in preferences) a splash is displayed informing the user that the app has loaded - and to look up to the menu bar, not down to the dock.
