How to freeze remote screen in TightVNC?

[Zhiqiang L. <zq...@ho...>]

Hi,

I am new for TightVNC and am using it pretty well. There's one thing =
that I haven't implemented yet. While I was accessing a remoate machine =
via TightVNC, I can not freeze the screen of the remote machine, so if =
there's someone there, they can actually see what I was doing, kind of =
losing my privacy. Is there anybody know how to freeze the screen of =
remote machine while using TightVNC?

thanks.
