Activate view client by sending a mouse event programatically

Hi,

I am using VMware view client version 5.1.0 with PCOIP. After connecting to a virtual desktop, when no activity is performed, a black screen is displayed after about 15 minutes of in-activity. Moving the mouse over the screen activates it again. What is reason for this behaviour. How can I control this idle timeout. Also, in such a scenario, I would like to programatically activate the session by sending a mouse event to the view client from another program. Is this possible?

Regards,
