/**
 * @brief Watcher class for IE5.5 and IE6.0 web browser windows.
 *
 * The window class hierarchy for a web browser window is:
 *      IEFrame
 *      |->Shell DocObject View
 *         |->Internet Explorer_Server (*)
 *
 * When we're dealing with pages with multiple frames, the web browser maintains
 * the window class hierarchy shown above, but nests multiple web browser 
 * (IWebBrowser2) elements within the document. When performing the HitTest
 * we (may) need to ascend the frame hierarchy to retrieve the correct element.
 * As we ascend the frame hierarchy we need to be sure to take account of the
 * offset of each frame within the document.
