I have seen this before, but wasn't happening for a while. The sequence follows:Slide pwr. HoldScreen blursPower Down pop upbackground dims.If I release the pwr slider before the background dims, the unit just goes to sleep.If I wait until the bkgnd dims, the pop up stays & I can cancel or power down. There are times that I have held the switch until after the bkgnd dims & it still goes to sleep, so that is not a definite. Like I said this has come & gone before & it may have something to do with other background activity, but nothing should be running. I am reporting this to see if it is a common thing, as I have the "insomnia problem" with mine. I don't know if they are related, probably not, but it is power dn/sleep related & I am trying to assemble all the clues. The other clue is that after screen time out, the unit goes into sleep mode after only 3 seconds. That didn't used to happen either. BTW I am running the Modified 7/24 firmware prior to the GE addition. Cheers,kev
