+ * here's how this dialog works:
+ * The main dialog contains a tree on the left (accounttree) and a
+ * deck on the right. Each card in the deck on the right contains an
+ * IFRAME which loads a particular preference document (such as am-main.xul)
+ *
+ * when the user clicks on items in the tree on the right, two things have
+ * to be determined before the UI can be updated:
+ * - the relevant account
+ * - the relevant page
+ *
+ * when both of these are known, this is what happens:
+ * - every form element of the previous page is saved in the account value
+ *   hashtable for the previous account
+ * - the card containing the relevant page is brought to the front
+ * - each form element in the page is filled in with an appropriate value
+ *   from the current account's hashtable
+ * - in the IFRAME inside the page, if there is an onInit() method,
+ *   it is called. The onInit method can further update this page based
+ *   on values set in the previous step.

+  - stop button
+    - showes up again after stopping detection and restarting it
+    - when stopping [retest]: buttons proper?
