Your Partner window displays one program at a time. It is easy to jump from program to program, but if you want to run a check-in program and a check-out program at the same time, you can open a second window and switch back and forth between them with a single keystroke.
To open a second window, simply double-click on the Partner (or AniTa) icon again and log in as before. If you can’t see the Partner icon on your desktop anymore, you may need to minimize the current Partner window first.
On a PC, press Alt-Tab to switch between windows. You can also use your mouse.
