Is there an enhancement program that will "fix" fuzzy pics?

Question

Sometimes when I take digital pictures there might be one pic that has perfect lighting, perfect background, but for whatever reason, the focus wasn't right on the camera. The picture might be one that can never be taken again because it was a once in a lifetime shot.

Answer 1

Yes, The Gimp can be used to enhance digital images.

Answer 2

Adobe Photoshop.  It is well worth the price.

Answer 3

Try Picasa2 from Google.

It's free and has a very efficient "sharpen" button.
