I just purchased the 7130 and the pen, and I am experiencing issues. For about 5-10min the pen will work perfectly but after about 5-10min it will then start to miss strokes or be slow to recognise the pen touching, the buttons on the pen will become less responsive and then stop working and then the pen will stop recongnising contact with the screen and then eventually it won't show the little cursor when you hover the pen around. If I leave it for awhile and then try it again it will work perfectly again and then the same problem occurs. I've tried putting new batteries in and the problem sill occurs.I am running windows 10 and using the silver barreled pen. It's disappointing as the reason I purchased this tablet was to be able to write using the pen.
