Funny thing is I am on here looking for an answer to the very same problem. Mine does not go up to the top left and sit there mine just freezes and i can't move the mouse anywhere with my fingers. I can use a keyboard and or mouse to nav around the screen, but while driving that is nuts. This has happen to me just lil more then 6 months ago. I just replaced the hard drive with a ssd drive thinking that was the problem and doing so i replaced windows xp with windows 7. I am lost, i go to Lilliput's web site http://www.lilliput.com.cn/en/service02.php to download the latest drivers and they don't download. I am confused, should i buy a new monitor?
Anyway just wondering if you had a fix for this i see no one add any advice that stinks.
