At Ease 3.0: Use Button Disabler To Prevent Sound Access

At Ease for WorkGroups 3.0 allows the administrator to keep students from opening control panels, specifically the Sound control panel. However, on the Macintosh Performa/LC 520, 550, 575, 580, 5200, 5300, and 5260 series of computers, there are volume controls on the front of the computer that still work even when the students do not have access to the control panels.

How can I prevent students from using these buttons to defeat At Ease?
System 7.5 includes a Control Panel called Button Disabler that can be installed with a custom system software install. This control panel has a single check box that, when checked, deactivates the sound and brightness controls on the front of Macintosh computers with built-in controls.

Use the Custom Install feature of your Macintosh CD to install the Button Disabler control panel, restart your computer, and click to place an 'X' in the box to the left of "Disable Buttons".
