While writing an email to a colleague today, Outlook 2003 underlined a passage and offered a correction.  The correction it offered didn't sound right but I clicked on it anyway to see if it looked better corrected.  It didn't.  But what I noticed next is that it again underlined the same passage and offered a correction, this time back to what it was originally.  Thinking it knows best (yeah, right), I clicked on it again and guess what?  It corrected back to the original passage and offered a "suggestion".

Original passage that "needed" correcting:



Corrected passage that also "needed" correcting:



The passage corrected back to the original:



And so I found the anomaly: The correction that corrected itself with a correction that needed to be corrected back to the original correction.
