ListMeister is opened in the standard Macintosh way: double-click on the ListMeister icon. (Tip: if you have System 7.0 or above, make an alias of the ListMeister icon and place it in your Apple Menu items folder. That way, you窶冤l always have fast access to your lists. If you have System 7 but haven窶冲 used alias窶 yet, see your Macintosh user窶冱 manual. Alias窶 are great time savers and worth the read, trust me.)
You close (quit) ListMeister by pulling down the File Menu and choosing Quit. Alternatively, you may click the main window窶冱 close box to quit ListMeister.
