[Mono-osx] Need a replacement for NSWindow.Close()

[Geoff Norton]

I think you're confused what .Close () does.  Since it specifically calls out it does not call WillClose either:

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSWindow_Class/Reference/Reference.html

Anyways, the issue with .Close is it does a .Release under the hood, that we aren't aware of, leading to a double free.
