I haven't seen this before. I was using One Note Metro to make notes from video lectures yesterday and every now and then in the middle of writing something the pen would stop responding and I'd be thrown out to the desktop. I had to restart the app. Anyone else had this?? I thought I'd hit the windows button but it wasn't that as usually that takes me to Start, not desktop and the app was not still running. It did it about 5 times over the course of an hour. Thankfully being a video lecture I coudl stop it until I'd restarted the app but it would have been an issue in a "real time" situation! It hadn't happened before so I wonder if it's to do with updates??
