You say "I haven't used Google Earth for weeks", which implies that you have used it in the past. On this computer?
Oh! For sure. I've wasted massive amounts of time with Google Earth. Maybe it has just been silently updating itself in the past, and I've never noticed. Now, it's silently upgraded itself to the Pro version (which is now free, apparently). I only found out because the installer plopped a shortcut on my desktop. I don't mind silent updates too much (or rather, I have had to get used to them, like everyone else). I would rather be asked if I want to upgrade, even if the upgrade is free. I suppose this is something else we've all got to get used to.

'They have been trivial, uninteresting, and full of error.'
