Yes, I have now been notified and said to download as the post above yours states I'm still waiting for it to even download it and install. I have been on-line for a little over an hour more than enough time for it to download an 1.8MB update file, but the icon isn't there any more.
This can go on for days waiting for it to actually be downloaded, when I first connect the WU icon will appear in the system tray and indicate downloading 0%, but it never seems to get started and just disappears for another indeterminate period of time before repeating the process all over again: icon appears, downloading 0%, doesn't get started and just disappears; icon appears, downloading 0%, doesn't get started and just disappears; icon appears, downloading 0%, doesn't get started and just disappears.
Eventually it will get downloaded and installed, so I think you can see why this process gets right up my nose. If nothing else it teaches patience
