Unable to change/set login text on Mountain Lion 10.8.2

[Google Code Exporter]

What steps will reproduce the problem?
1. Open secrets pref pane and go in the tab All Secrets
2. Type in the box also a simply word like welcome and hit enter
3. Shut down and restart your MAC: the "welcome" word doesn't appear and still 
show the old word

What is the expected output? What do you see instead?

The previous word I set and exactly "this is a stupid MAC"
What version of the product are you using? On what operating system?
Mountain Lion 10.8.2


Please provide any additional information below.

the box to type is Login Window text in "All Secrets" tab.
It doesn't work.
I uninstalled and reinstalled secret without success. Any tip?

I solved using terminal.
write down in terminal:

sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText 
"OSX is  retard" 

Replace "OSX is retard" with the word you want.

This tip is more than five (5 ) years old and in secrets doesn't work. Secret 
so oblivious? Baaaaa...
I can admit for latest OS X versions but for a really old tip that doesn't work 
in secrets but works perfectly in terminals it push you to trash secrets.
If a so simply tip doesn't work I let you imagine what can happen with more 
hard hack...   :/
