SOLVED!
Posted to help others who may experience this!
First... thank you to Dan and Heath for working with me on this issue... and especially Heath who provided me an upgrade to my DVR. Turned out that there was no issue with the DVR, but it is nice to be running the latest firmware!
The issue was a simple newbie error all along! NOT the fault of the DVR.
The problem was my target was too small. Hard to click on a sliver on a timeline with a mouse.
My screen shots tell the story better! All is good again... unit works as advertised!
