I didn't ask, Lisa did, but I don't see anything in the recently installed list that looks like a candidate for being the problem.

Where did the list in post #22 come from? Are those the windows that are opening up? I thought they were apps opening but everything on that list is Finder.

How do you close apps? I ask because just clicking the X in the window does not quit the app, just pushes it into the background. That means it is running when you shut down so if your settings are to re-open what was running, even though you cannot see it, it is running and will restart.

And can you say exatly what is opening? You listed a couple but I haven't seen a list of what we are talking about. Thanks!
