I got no notice about this. Tray icon was blue. I just happened to hover the mouse over the icon and it said that PG was initializing...huh? So, I brought it up and it said that the driver was missing. I don't know how that happened. Bringing it up froze the screen, froze Windows. Sigh. I had to call Task Manager and force a shutdown. This meant that I lost 31 tabs in Fx that I could not tell Tabbed Browser Extensions to save before closing Fx. And I lost all the work I was doing in MS Digital Image in making an album and collage. But what really concerns me was that I got no notice that PG was not running properly! Plus, what would cause the driver to be missing? I assume I need to uninstall it and reinstall it? After rebooting, the driver was still missing. So, I exited it.
