I am evaluating TeamViewer for my need to access unattended device. It seems if I access the remote device from different machines (each time logged in to TeamViewer with my user account) - they all connect - but only one machine is able to control the remote device. For the others it shows on the unattended machine a mouse pointer with a slash through it. What can I do to allow my account to access the unattended machine from more than one machine (at different times) to the same account?
