More info: After a few minutes of I trying to use this (basically unsable :-( ) TDE, it suddenly popped up a dialog that said that the screen was locked and requested that I enter my password. When I did that, I was returned to the session, but the flickering had stopped. So that suggests the question: what causes the screen to lock and the popup requesting unlocking to appear? Somehow that seems to be related to the flickering problem. Doc PS I have no screensaver set. -- Web: http://enginehousebooks.com/drevans
