If you have a window which is not being controlled by a window controller and whose releasedWhenClosed property is true (default for NSWindow), then it will be released when it is closed (unsurprisingly). Therefore, you should not release it again yourself or you will over-release it and cause a crash (or worse).
The easiest thing to do is to always turn off releasedWhenClosed so that window objects obey normal memory management conventions.
