Newer Widgets can supervise themselves. A Widget can start to perform an operation such as using your computer's file system or accessing the Internet. If an action isn't on the Widget supervisor's list, the supervisor stops the Widget.
The dialog box that shows up the first time you run a Widget lets you know if that sort of supervision is in effect.
Older Widgets might not have the supervisor function set up. In this case, we let the Widget do what it wants, although we tell you that we're allowing it full rights the first time the widget runs. It's up to you to decide whether to let Widget to run.
