John,

  I responded to your email, but I attached a file. I'm not sure if emails with attachments get through to the NAMD forum.

Kelly,
  This is undoubtably a limitation of the ORCA log parser.
Can you provide us with example files the demonstrate both the
working and non-working variants you've encountered?
