MOBHack question

[Karagin]

In MOBHACK in the bar below the File and Help line there is the Features button to do the things in MOBHACK, on the far side of that there is a button that say you can Search and Replace a word/names.

It doesn't work, or it doesn't do anything. I checked the help file it tells me to type in the name I want to replace with what I want but when I got to it and type say Team to Section for example, nothing happens.

Window opens it says Search and Replace and has two section for Replace (Area to type word)
With (Area to type word)

The OK and Cancel boxes to the right of that and below all of that is (Case Insensitive).

Now the Help File shows a check box in place of that but no check box is to be found.

Not sure which or what is right, so I am asking.
