I have been having the clicking by itself problem on and off since I purchased the ASUS EP121. A few months ago I read through these posts and tried to figure out what triggered the behavior. ASUS did say I could send in my tablet to be "fixed", but I was nervous about doing that, based on some of the problems I had read about. After trying changing the screen display resolution to avoid the upper right corner (found out that there are resolutions that you definitely want to avoid!), removing the touchpen, rebooting, etc. I have stumbled onto something that I still can't believe is working for me (for the last 3 weeks, don't know if the clicking by itself will eventually come back). Get this - I removed the tablet cover that also serves as a tablet stand! Every since I did that, I have not had the clicking by itself happen once! I can now keep my windows full screen, without having them close when the clicking begins to happen. Don't ask me why and I don't know if this will work for anyone else, but I thought I would offer up my experience because it was very helpful to me to know that others were having the same strange behavior that I was. Please let me know if you try this and it does or doesn't work. I have worked with a lot of computers over the years and am curious as to why this would work (heating issue when the cover is on?).
