Dear J�rgen, I meant put a sleep statement elsewhere for test purposes.
Anyway, other things I have briefly tried. I currently use gzip 1.3.2, but also tried 1.2.4, with similar results. Once, and once only (first time I tried with 1.2.4), it did the whole folder correctly. I thought, for a moment, I'd found the issue. It also happens, apparently identically, if one copies, or moves emails from the folder to the archive. Regards, David Pilgram.
