For some reason in my Cocoa application when I resize the parent window, the drawer doesn't move with it. It just stays where it is on the screen and is detached from the window. I built it using the "Window and Drawer" object and I think it used to work. Everything else about it still works fine (i.e. toggling, etc).
I have compared all the attributes to a fresh "Window/Drawer" object and everything looks okay.
