Hm, I should probably use this instead of my bespoke solution for
OnAppWindowClosed.

+  var data = chromeHidden.appWindowData;
+  if (!data)
+    return;
+  data.x = info.x;

[jeremya, 2012/10/19 00:26:45]

Perhaps this should be in data.bounds?

+  data.y = info.y;
+  data.width = info.width;
+  data.height = info.height;
+};
