odd? PCX file without colour information turns op with colour?!

Can someone tell me how to get ridd of all colour information in a PCX file. This file is opened by someone with microsoft paint. The file should be colourless (grayscale) but somewhere in the menuoptions you can see that the file has colour information.

An old MS-based program needs that image but only can read pure black and white info.

I wan't it plain and simple black and white, but can't get it that way... I was thinking bitmap, but that totally trashes the pic and makes it too big!

Hope someone can help!

Later,

Max

note::>> reply used to be because I thought it worked, not to be impatient!

There was a function in paint to set it from colour to black and white... it *edit* doesn't *edit* work..

Anyone knows a way to export a .ai / .psd file to a black/white pcx file under dos

Later all,
