1) In XP, I select log off, switch user, then I am returned to the main windows screen / welcome page.
2) The user accounts are displayed, but the one I am logged on to does not show me as being logged on.
It used to show who was logged on, but not anymore.
3) I select another account, this is followed by a brief glimpse of the desktop wallpaper in the account
which is already logged on, then a return to the welcome page.
So, it seems that I can no longer have multiple users being logged on at the same time.
The same thing happens if I leave the PC for a while, then return to the main screen by
reactivating (i.e. by moving the mous).
I've noticed that the PC is quite slow starting up these days and also there is an occasional
error message when shutting down. I haven't been able to capture this error message as it disappears
too quickly, but it is along the lines of being 'unable to read something in the registry'. I have
no way of knowing whether this contributes to the problem, but I thought I'd mention it.
Any advice gratefully received.
