[TYPO3-RTE] Can one hide the about-button?

[Christopher]

Hi!

I have configured the RTE to show only the buttons which I have allowed in 
the user-TSconfig:
options.RTEkeyList = bold, italic, underline, left, center, right, 
orderedlist, unorderedlist, link, table, justifyfull, insertcharacter, undo, 
redo, findreplace, image, superscript, removeformat, justifyfull, 
strikethrough

But the about-button is showed anyway....

Is there a way to hide it?
