Since some mystical update in the past...most of the time when I power up my S3 now, the cursor is missing in action. If I unsnap the keyboard and snap it back on, the cursor is there with no further problems. This happens maybe 80% or 90% of the time after powering up my S3 from its off state. Anyone know if there's a way to correct this, or is this just another of MS's ethereal issues with W10 and Surface devices??
