FYI
I had several refreshing images on my control pages that were images on my server. I had referenced them as "File:///...." After I updated last night, all my control pages that used a image from the server computer were showing a blank screen and my log file was a never ending list of web server issues about opening a "File:///..."
I changed my url to "file:///..." and all is working fine now.
I don't think the "H" addresses are case sensitive... all of those links are still working fine and I didn't have to mess with them.
