At Ease 3.0.1: Can‘t Lock Power Macintosh 7200 Hard Disk

I cannot lock the startup volume with At Ease 3.0.1 running on Power Macintosh 7200 computers with System 7.5.3. The option is available in the User Settings menu, and is checked, but I can still start up from a CD-ROM disc or floppy disk and access the hard drive.
This issue is resolved in At Ease 3.0.2, which is available on the online services.

Once you update to At Ease 3.0.2, you should disable the Lock StartupDisk feature, quit the administration application, and then re-enable Lock StartupDisk. This will ensure that the latest update code is installed on your startup disk.
