CS4 PCX File Pixel Aspect Ratio ?

Hi,
when I Import PCX Files I get the message that Pixel aspect correction is for preview purposes only. Turn it off for maximum image quality.

How can I disable that per default so that all pcx files I import are displayed correct?

Your PCX files have resolution information in them that says they have a non-1:1 aspect ratio, and Photoshop is honoring what is in the files.

There is no way to turn it off permanently short of fixing the files.
