Has anyone had any progress on this. After installing the anniversary update, my dell pen stopped working. A few days later my touch support also stopped working. Sent it in for repairs after no one could fix it remotely and the spectre stopped recognising itself as a touchscreen computer?!!! They replaced the entire LCD and said it was a digitizer failure. Touchscreen now works but dell pen no longer works. I am 100% sure this is something to do with the update. Anyone figured something out yet?
