Check out this fun bug... Sometimes when I wake the SP3 from sleep, I get this crazy cursor behavior where the cursor jumps to a certain part of the screen and begins moving up and down like crazy in a little area on the screen. Usually the behavior disappears after a reboot, but when it happens it is TOTALLY driving me crazy. If you watch the video...I'd highly suggest doing so in 720P or the cursor/touch will be difficult to see on the blurry video.
