I don't know what Robot's problems are, but I can't stay connected to the Internet in either 10041 or 10049. I tried my best to work with Spartan, but like so many others, I finally had to give it up. Even when I tried to open a PDF file, it would open in Spartan! How rude is that!?
So, although it's working fine for you (you must have a system just like one of the devs ) it is not working fine for many of us, and we're only the tip of the iceberg. Just go to Feedback and drill down on any subject and you'll see what I mean.
