My 1010b updated to AE a couple of weeks back but I've noticed now that if the machine boots without keyboard dock attached then touching the screen to input password no longer brings up the touch keyboard, I can get around this by clicking on the accessibility / on screen keyboard to input password. The touch keyboard isn't working in Windows either when I click on a text box.
Have also noticed that when I disconnect the tablet from the keyboard dock that it's no longer switching automatically to tablet mode, I can do this manually but it seems to me that something in the latest Windows update has banjaxed setting(s) or drivers.
Have any of you had the same issues since Windows upgrading? I've looked online and tried a host of recommended solutions but no joy, it's not the end of the world but is very annoying.
