It's a trick question, right? A search of Help in Excel 2007, 2003 and 2000
for "Information Box" gives null results.
There are message boxes, text boxes, list boxes, and boxes that are simply
boxes - but nothing formally known as an Information Box that I can find.
If we knew when/where you are supposed to see this information box, then we
might be able to give more assistance.
I'll take the first WAG at it and shoot at the information that you might
see in a Message Box: prompt, buttons and title. There are other 'invisible'
attributes such as associated help box and context, but those three are what
the user would see on screen when it was displayed, and each of those items
could be separately identified.
