Thanks Benjamin. I spent the rest of the day today, running it under Windows. Eventually, after a couple of hours, I was able to reproduce it under Windows 8.1 too. That led me to check Lenovo Support Forums. <a href="https://support.lenovo.com/in/en/solutions/ht103512">https://support.lenovo.com/in/en/solutions/ht103512</a> <a href="http://laptopmedia.com/news/lenovos-solution-to-the-yoga-ghost-touches-problem/">http://laptopmedia.com/news/lenovos-solution-to-the-yoga-ghost-touches-problem/</a> <a href="https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/ll06_en/page/10/thread-id/26944">https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/ll06_en/page/10/thread-id/26944</a> Almost the entire Yoga series seems to suffer from the problem. Lenovo stated in some of the threads that it may be a software problem. But I doubt that. Let's see... I'm going to try a couple of sw fixes, with very less hope. Thank you for your time in analyzing the logs.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
