Adrianh, Tachyon and Aging Acolyte, Thanks to you guys I finally got the file upload nightmare saga solved - thanks very much for your help, all. I put in all the error checking that you suggested & re-wrote the code in a mini version that finally began to work, to my surprise & delight. The working bit of code looks like this: 
open(OUTFILE, ">$UPLOAD_DIR\/$file_name") or die "Upload failed ($!)";

  binmode $fh;
  binmode OUTFILE;

  while ($bytes=read($fh, $buffer, 1024))
  {
    $bytes_read += $bytes;
    print OUTFILE $buffer;
  }
  die "read failure ($!)" unless defined($bytes);

I think the last line is that bit that made the crucial difference. I didn't know that about 'read'. Anyway, thanks again, your help is very much appreciated. Wish I could get you all a Monastery mead!
