I replied to this problem on another thread......
I found I could trigger this event....'Autorotate on'/'do you want to switch to tablet mode '.....by going to the 'Store' and checking for updates (check for updates 2 or 3 times would invoke the issue).
Strangely enough, I could not reproduce the errors (as above) when the clipboard was attached in reverse (the screen is attached to the base but reversed... i.e. if I closed the lid the screen would be on the outside).
Can you reproduce the same results?????
