Really bad fringing with nikon d5000?

I have been having a real problem with my nikon d5000 recently… Fringing. This is using the 18-55mm kit lens. I'm shooting RAW format so i suppose there's no in camera correction. The really horrible thing is that all the fringing is always cyan, red, green, or a nasty combination of all of them which photoshop elements 9 does NOT detect using the 'defringe' layer option. I have tried manually desaturating these colours but usually end up with a horrible big grey line where the fringing was.anybody know how i can easily correct the fringing using elements 9? Or is there an option i have turned off on my camera.

please help!

Added (1). Yeah, i know you can do it in lightroom 3, but i don't have it… Please tell me a way to do it in elements?

If you are using Lightroom 3, you can correct fringing caused using the lens correction in that program

The design of the lenses has more effect on how much the fringing effects your images.

Right, defringe should be done in RAW processing. That means when you open up your NEF file with PsE you should have a "Camera RAW" window pop up, in one of the sections for this, there should be a Tab for "Lens Corrections" In that you should have options for "Chromatic Abberation" in which there's a "Defringe" option.

Try shooting in JPG. RAW is overrated in most cases and in-camera processing often eliminates chromatic aberrations for JPG imaging.

Also consider upgrading that lens if shooting in RAW is important to you. The 18-55 has issues with CA.

EDIT: YOU CAN DOWNLOAD AND USE A TRIAL VERSION OF LIGHTROOM FROM THE ADOBE WEBSITE. +1 ON THE OTHER TWO ANSWERS.
