Enabling and Disabling Local Input
Use Disable input to disable the mouse and keyboard on the controller machine during the session.
Local Input is available only during an Active session.
The Disable input icon 
is available
when the use of the local keyboard and mouse is enabled. Click the
icon to disable local input. Click the icon again to enable local
input.
Note: On opening the controller, local input is set dependant
on the type of session. During a remote control session, to use your
mouse and keyboard to access the target desktop, local input must
be enabled. However if the target user moves the mouse when local
input is enabled, you are temporarily blocked from sending any input
events to the target until the target user stops moving the mouse.
The icon changes to a blocked mouse image. When switching from an
Active session to another session local input is disabled.
