Upon first login off a boot one of the users is faced with a nonresponsive desktop. Things like the menu are clickable but nothing happens, progs cannot be launched etc. This also means that bailing out is possible only via Alt/Cntrl/Bckspc. After that on the second and subsequent logins the problem is gone …until the next boot.
I looked over the user folder for unusual files or whatever might seem out of whack, can’t see anything. Other user logins do not have this problem.
