The current number of users logged onto the main computer is shown. If you want to see which computers are logged select the Tools->Logged on Users menu option. You can also send a message to any other user currently logged onto the same PC. This can be used to pass on information to someone who has an order locked that you need to work on.

If there are problems with your license being used by another PC on the network you can clear the existing information by clicking on the Reset Logged on Users button.
