Folks,
Thank you for your suggestions, I looked at all of them. What was missing, I wasn't able to find exactly what I needed to do to restore the missing features. I finally deleted the program and what I could find of the residual files under user & finally deleted the few Dlls in the installation folder & left the registry alone. I reinstalled the latest Musicbee and when I re-directed the scan to my music drive, it scanned and said no new files were found so the index remained somewhere, probably in the registry. I also had to tell the Audio Output to use the ASIO & McIntosh driver as opposed to the defaults, but wonderfully, the missing section was restored.
Now the drop-down Header Menu is back and I see where the top option is "Hide Header Menu" I must have clicked that. There must be an easy option to make it appear & I'll search for how to restore that so I won't have to do this complete restore again if I once more misclick.
Thank you for the help.
