If I am doing things on a remote computer and I want to switch back to my computer to show the other person something and then switch back to the original remote computer can I do this and, if so, how?
Right now you can't stream your screen to a remote user with just one button. Sorry for that.
You can use portable Viewer on a remote computer and Agent on your local machine for that. Just the regular connection. You can allow just "View only" mode on Agent to be sure that remote user can't do anything but observe.
But it is a really good suggestion! We will consider it and possibly add to our wish list.
