Dammit. This has been happening to me as well and this morning after first starting the device it did it for 30 seconds or so. - Browsing the web or using kindle - Show desktop is activated - Touch back on the open program - Show desktop is activated and I can see the screen dot appear to the bottom right. If it carries on I might decide to get rid after returning for a repair. (Boxed and ready to go back, case created, and just waiting for a reply) ... after thinking about it for awhile, i think I'll start looking for something else as after reading the above information, I don't want this machine if it had a problem so soon.
