one pixel wide black line around dds file

Hello,

Am wondering if someone can help me finding out what I might be doing wrong.

First of all, the problem might not be caused by Adobe Photoshop settings, but I've been unable to find an answer elsewhere.

For some game skinning I need to save files as a .dds, when I do that using photoshop and the nvidia plugin with every file saved as .dds there's a one pixel wide black line around the entire image (the outer pixel of the original image, not an extra line), when I save the same file as jpeg, psd or bmp it doesn't happen.

For larger files it doesn't matter that much, but for smaller ones I have to switch between programs (paint.net) to work around it.

I have tried all variants of dds and that didn't make a difference.

For most pixel related things I use the standard settings.

Hope someone can help, thanks in advance.

Cheers,

Rob
