UltraVNC

I am having problems with disabling local inputs and blanking the screen.

I have the following setup

windows 7 ultimate laptops connected to wireless router with ultravnc installed on it

I am able to blank the screen and have a picture saying it has been locked but i would like it to be able to ...

How do i configure the settings so that i can blank the screen when i dont want anyone to see what i am doing on the machine and so that i can disable the local inputs so that they cant fiddle around with the mouse or keyboard when i am trying to do something

Hi there i use ultravnc and i am wondering if you can disable inputs on the remote machine aswel as being able to blank the screen

And also if you can blank the screen then close the program and then open the program again later to unblank it
