While I do indeed love my SP3 there is one thing that regularly drives me nuts and for which I already wanted to throw it out of the window several times: it constantly "looses" the pen! Meaning: I am, say, happily inking away and taking notes in some meeting, then I am resting for a few seconds e.g. to follow the discussion and when I want to continue inking and take notes, there is suddenly no reaction from the tablet. It does not react to the pen any more! Keyboard or mouse are fine, but the pen is ignored: i.e. the cursor is not following it, the pen's buttons don't show any effect. It is, as if bluetooth suddenly got disabled and/or the pen disconnected or unpaired. And indeed, often - if I bring up the bluetooth settings and quickly disable/reenable BT - then the pen is back again. I can then ink and point again etc. only to witness the pen suddenly AGAIN not working any more a few minutes later. Sometimes this happens in mid-inking. Suddenly no reaction to the pen any more! This is SOO distracting, frustrating and over time really maddening! As I had to learn it is obviously the tablet's "fault", not the pen's. I first suspected the pen to have an issue. A new battery didn't help. Then I bought myself a second pen, just to witness the exact same infuriating effect with it as well. So I conclude: It's apparently the tablet that causes these connection losses. Any idea anyone what could cause this? Could the pen driver be constantly crashing or any other plausible reason? Any solution or workaround anyone?
