Please use objective C naming in objective c files
desktopRect and windowRect

CGFloat x = (NSWidth(desktopRect) - NSWidth(windowRect)) / 2;
CGFloat y = NSMinY(desktopRect);

Aside from that, is there a problem that the user may start with their dock
hidden, and then a malicious remote operator could turn the dock on, and make
the local user be unable to reach the disconnect window because the dock will
block access to it? (hopefully that makes some sense).

+  int y = desktop_rect.origin.y;
+  [[self window] setFrameOrigin:NSMakePoint(x, y)];
 }
