Our operating system is Windows XP. If a user is logged on to a site through internet explorer and another user comes to the computer and switches users to the new user, the new user cannot use internet explorer until the first user closes all open internet explorer windows? All other programs, both users can use simultaneously, ie Excel, Word. This is a home computer.
I downloaded Opera and two users can use it at the same time. I was pleasantly surprised how easy it was to establish my old multiple tabs to connect to multiple sites right away; not to mention the ease to import favorites.
