If you use AppCan XP with multiple logins, you can quickly change to another account by selecting ‘Options’ on the Apps screen and then selecting ‘Change User’.

This will offer you a list of other logons you have used on the device.
Select the required account and enter your password for that account (your username will be automatically completed for you).
Note: Change User will not be available if you have only logged in with a single account on the device.
