BTW, yesterday I had so much trouble trying to post my pix, the computer was running dog slow from updates in the background and when I moved the laptop outside for a cigar the screen didn't come back on so I had to force a power off and reboot to get the screen to come back. It's working better today, one upgrade pending.
