Limited Control Panel Usage in Classic

Some Mac OS 9 control panels configure system components that are already configured by System Preferences in Mac OS X. When Mac OS X detects a redundant control panel during Classic startup, it does not load the control panel. However, redundant control panels are still visible in Classic when you choose Apple > Control Panels. If you try to use the Mac OS 9 version of a redundant control panel, you will see an alert prompting you to perform the task in Mac OS X System Preferences instead. You should also be aware that third-party control panels and extensions might not work properly in Classic. Contact the third-party vendor to ensure compatibility.

Use General Controls in Classic to avoid managing two Documents folders. In the General Controls control panel, select "Documents folder." This sets the default save location for Classic applications to the ~/Documents folder.
