LR 6/CC now only opens at VGA resolution

[rebadurchee]

Not to be a litany of problems, here, but this is weird.  All of a sudden my new LR CC opens at what I can only think is VGA resolution.  Everything is HUGE.  The panels crowd out the images in the middle and it is impossible to use.

Here's what I tried:
  Updated my graphics card driver
  Turned GPU on and then off - happens either way
  Rebooted 
  Tried to find something in Control Panel (I use Win 7 64) but nothing.
  Tried to use Ctrl-mouse wheel 
  Tried to use Ctrl- minus sign
  Tried every other application I have, including PS CC 2015, and all work just fine at 1920x1080
  Tried to find something in LR preferences, nothing that I could find

Any suggestions would be greatly appreciated!

Thanks,
Stilson

It took a very long chat session with Adobe but after trying everything else we uninstalled and reinstalled LR CC and that fixed whatever was messing up the screen resolution.  Ghosts in the machine...
