From the usual 'Welcome' screen, I click on the icon for my user account as I always have done in the past; now, it goes, like normal, through the sequence where it says 'Loading your personal settings' and after a few seconds, the typical desktop screen appears, if only for 1/2 a second, and then the blue welcome screen re-appears with the user icon again, this time showing 'Logging off....' and then 'Saving your settings...' From here, it might as well be perpetual motion...thanks in advance for any possible assistance here....paul b.1 person needs an answerI do too
