Normally, Sandboxie inserts the Sandboxie marks [#] in the title bar of windows associated with sandboxed programs.
Note: It is not possible to enable both checkboxes at the same time.
Sandboxie can also draw a colored border around the active (foreground) window, if that windows belongs to a sandboxed program. Use the third checkbox to enable this behavior and choose the border color for programs in this sandbox.
