Touch Cover problems?

No, it isn't splitting on me, but I'm having problems with the Touch Cover.

When it is asleep with the touch cover on, I flip the kickstand out, lower the cover and then it decides to either type one letter repeatedly or bring up the onscreen keyboard. Usually, if I detach and reattach the cover, it will be ok again, but then it falls asleep, I wake it by tapping the windows capacitive key and then "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb".

Anyone else experiencing this or should I just head to a Microsoft store and have a chat with them?
