newline processing problem?

I have some code which generates a large string to be used by the mail() function. At the same point in the string each time, PHP stops processing "\n" correctly and instead of a newline outputs nothing, so the text starts to get run together.. but it doesn't seem to happen on every "\n". Has anyone else run into this problem? It used to work correctly but I made a few changes to portions of the code that were totally uninvolved, and it started behaving this way. Unfortunately, I didn't notice the problem until I'd made a number of small changes to unrelated things and didn't remember what they were. Gordon Morehouse nphyre@evernex.com www.evernex.com
