Gurus,

Brainteaser.  Create a new text file on your desktop. Ensure file extensions
shown under Explorer's View options.  Then, change the extension of the text
file from .txt to .cnf.  The result will be an icon that looks like a speed
dial icon, with no extension.

Question - so why does the extension .cnf become invisible?
