Using the viewer window
The viewer window gives you the ability to view and control the CPU IP and its
host computer(s). Its operation is almost identical regardless of whether you
used the VNC viewer or your Web browser to display it.
The menu bar
The viewer window presents a menu bar similar to that shown below. Certain
items within the toolbar are displayed depending upon your access permissions
and/or the CPU IP configuration.

When using the viewer window
What is the best screen resolution to use?
The best resolution for your computer is one that is larger than the screen of
the host computer that you are viewing. This will allow you to see everything
without scrolling around, as described next.
How do I navigate around a larger screen?
If the screen that you are viewing has a larger resolution than your viewing
window you will need to scroll around to see all items. The viewer window
allows you to 'bump scroll' (only in full screen mode). This means that when
your mouse cursor bumps against the edge of the screen, the screen image will
scroll across automatically.
How do I escape from full screen mode?
Press the F8 button. This button is changeable but is most often set to F8.
Why is the

This happens when a new host screen is viewed (that has not been viewed
before). Click the

for important information about this feature.
How do I change between host computers?
The best way to change between host computers is to click the 'Hosts' button
and then select the required computer by name. See
How do I remove traces of moved items from the screen?
When you move an item or window across the screen, sometimes it can leave
unsightly trails. These are called artifacts and can be particularly prevalent when
the connection speed is low. To remove artifacts, click the 'Controls' button and
select the 'Refresh screen' option. See Controls.
How do I make the most of a slow connection?
The VNC viewer is slightly better suited to slower connections than the browser
viewer because it offers more options. Click the
viewer when entering the CPU IP address during log on.
