Win 10, 64. Galaxy started to log out on every startup. About a week or two ago. Probably, closing down the app before the shutdown helps. But I don't really want to exit it every day. Same as I don't want to fill the password every day.

Some additional details: I found out that Galaxy fails at first login after the startup. No matter, how much attempts to log in I will do - it always fails. I need to close the program, launch it again and then log in successfully.
