> They have only one such editor, and it doesn't work in Windows (quite frankly, I'm surprised that the DOS version of CnC runs on WinXP...). Any other suggestions?

Hmm, I remember using an editor that would run under Windows (and was actually written for Windows), but I don't have it now and can't tell you where I got it Try to set the compatibility for the editor you have to match Win95/98, maybe then it'll work?
