Timbuktu Pro Control and Observe sessions take place in a screen-sharing window, which displays the remote computer’s desktop on your screen. The Observe/Control Guest tab in the Preferences dialog box lets you control the appearance and behavior of the screen-sharing window. You may specify options that may improve screen-sharing performance and security during screen-sharing sessions.
Timbuktu Pro also supports secure screen blanking. Secure screen blanking is a Timbuktu Pro security feature that prevents unauthorized viewing of your computer’s screen while it is being controlled by a remote user.
To change your Observe/Control Guest preferences
From the Setup menu, choose Preferences.
In the Preferences dialog box, click the Observe/Control Guest tab.
In the Window area
Select Automatically Scroll to scroll the screen-sharing window automatically when your mouse pointer approaches the edge of the window or when the pointer on the remote desktop moves out of view.
If this option is not selected, automatic scrolling will not occur. You can scroll the window manually by clicking on the scroll bars at the edge of the window.
Because there are no scroll bars when a screen-sharing window is maximized, a maximized window always scrolls automatically.
Select Show Scrollbars to display scroll bars in the screen sharing window. (When the screen-sharing window is maximized, scroll bars will not appear, even when this option is selected.)
Select Always On Top to force the screen sharing window to remain on top of all other application windows.
Select Start Maximized to start screen-sharing sessions with the screen-sharing window maximized.
Select Shrink to Fit to shrink (or enlarge) the image of the remote desktop to fit entirely within the screen-sharing window. If you reduce or enlarge the window, the remote desktop will resize automatically to fit. However, the remote desktop will never be enlarged beyond its actual size.
In the Keyboard area
Select Map Control Key to Command Key to specify that your CTRL key acts as the COMMAND key when you control a Macintosh computer.
Select Use Logical Keyboard to use logical keyboard mapping if the host and guest computers use different keyboard types. For example, if the host computer uses a Qwerty keyboard and the guest computer uses a Dvorak keyboard, pressing the Y key on the guest computer will have the same effect as pressing the Y key on the host computer.
Physical mapping, which is used if this option is not selected, maps keys based on their physical location on the keyboard. For example, if the host computer uses a Qwerty keyboard and the guest computer uses a Dvorak keyboard, pressing the Y key on the guest computer will be translated as a T on the host computer.
Select Synchronize Lock States to match the CAPS LOCK, NUM LOCK, and SCROLL LOCK settings on the host computer to the settings on the guest computer. This matching occurs as soon as you press a key while the screen-sharing window is in focus.
If this option is not selected, the host computer’s CAPS LOCK, NUM LOCK, and SCROLL LOCK settings will not change.
In the Security area, select Blank the Screen to activate secure screen blanking when you Observe or Control another computer. Secure screen blanking is a Timbuktu Pro security feature that prevents unauthorized viewing of a computer’s screen while it is being controlled by a remote user.
Note: Screen blanking will occur only if the host computer allows it. If the Blank My Screen when Users Control My Computer setting is enabled, blanking will occur whether or not you request it. If the Blank My Screen setting is not enabled, the screen will blank only if the user of the host computer has enabled the Allow Controlling Users to Request Screen Blanking setting.
In the Capture Technique area
Select Use Accelerated Capture to use the video-driver-based remote control component, which increases Timbuktu Pro's screen-sharing performance. Clear this check box to use the Universal Remote Control Adapter, which makes Timbuktu Pro more compatible with different video cards and video settings.
The Universal Remote Control Adapter also supports systems with multiple monitors. If you have a multiple-monitor setup, disable the Use Accelerated Capture option.
Select or clear Use DirectDraw to enable or disable the use of DirectDraw (which allows Timbuktu Pro to send screen information directly to the video adapter). In most cases, you will not need to disable this option.
Select or clear Use Hint Provider to enable or disable the use of Hint Provider (which allows Timbuktu Pro to access application messages). In most cases, you will not need to disable this option.
If these settings are not enabled on the host computer, but enabled on the guest computer, the guest settings will be used during the screen-sharing session. However, if these settings are enabled on the host computer, the guest computer cannot disable them.
In the Presentation area, select or clear the appropriate checkboxes to set options as desired.
The Presentation settings allow you to control the appearance and behavior of the remote desktop while you observe or control a remote computer. Most of the Presentation options, when selected, will increase the screen-sharing performance of Timbuktu Pro during remote-control sessions.
Disable Desktop Wallpaper removes the Windows wallpaper from the host computer’s desktop when you are controlling or observing the computer.
Disable Active Desktop disables Active Desktop on the host computer when you are controlling or observing the computer.
Disable Animations disables desktop animations on the host computer when you are controlling or observing the computer.
Disable Full Window Drag disables full window drag (in which the window’s contents are displayed while it is dragged) on the host computer when you are controlling or observing the computer.
Disable Screen Saver prevents the screen saver from being activated on the host computer while you are controlling or observing the computer. (For example, if the screen saver is automatically activated after a short idle time, it may activate during your session if you are idle for a brief period.)
"Kill" Screen Saver deactivates the screen saver on the host computer at the start of the remote control session.
If these settings are not enabled on the host computer, but enabled on the guest computer, the guest settings will be used during the screen-sharing session. However, if these settings are enabled on the host computer, the guest computer cannot disable them.
In the Presentation area, select an option from the Filter drop-down list. The Filter option forces a color-depth reduction before screen-sharing data is sent from the host computer to your computer.
During your remote-control session, Timbuktu Pro checks the Filter setting on both the host and guest computer. The more restrictive (faster) setting is used.
Click OK to save your changes and close the Preferences dialog box.
