Use WebDAV folders on Windows Vista

Several old ways of using WebDAV folders on Windows XP don't work on Windows Vista. I find a new way today:

1. Open "Computer", which is probably in your "Start Menu".
2. Click .
3. Do NOT click "Connect to a Web site that you can use to store your documents and pictures." Select a drive letter. Fill in the "Folder" blank with modified website address. The modification rules are:
   • If the original address is like "http://example.com/folder", then the modified one is "\\example.com\folder".
   • If the original address is like "https://example.com/folder", then the modified one is "\\example.com@SSL\folder".

4. Click "Finish" and you can see your WebDAV folder/drive in "Computer".

This works on my machine, to the extent that I can browse the web folder in Explorer and open files. However, Word will not save files to the web folder, although it can see it and I can browse to a folder within it.
