Also, you can sign on to as many computers as you want if you have AC on a server or main computer in your office. You just can't have more than one chart open at a time on any computer.
However, if you are in a room, logged in on a laptop (or a wired desktop if you really want that extra hardware) and also logged in on a machine in your office, you can remote (RDP) to the office on your laptop, and then have two charts open simultaneously. Sometimes that is actually useful. Just takes practice to keep straight where you are if you have a lot of windows open.
