The Task Panel is an interface to jobs started by Chimera. It provides information on previous and currently running jobs and allows canceling background tasks.
There are several ways to start the Task Panel, a tool in the General Controls category, including clicking the information icon in the status line. The icon will be grayed out when no background jobs are running, but clicking it will still show the Task Panel.
Clear Finished removes listings of any canceled or finished jobs. Help opens this manual page in a browser window, and Close dismisses the dialog.
