Boots errors are back but now when they appear they sometimes behave differently, they show and go away without me having to push the space bar several times like I did yesterday. Sometimes they don't show at all.
I find today's lack of consistency disturbing.
I forgot to mention I have configured a map to a network drive, I have no idea if that matters and I can't see a difference unplugging the ethernet cable.
I'll keep it as it is for now, sorry for taking over the thread.
