My copy of NetFinder is missing menus. Is the application corrupt?
No. NetFinder will show you the most commonly used items when you click in the menu bar. However there are items that are less commonly used which are available to you as an “option” when you press the option or alt key on the keyboard. Try it now, you will find lots of useful additional commands. Note, although the menu is not shown by default, many have an associated keyboard shortcut assigned to it so you can simply press the keyboard sequence to initiate it. You may even want to press other modifier keys (control, or shift) while pressing the option key to see if there are even more options, however this is very rare.
