Hi there, I'm experimenting with Jalview as Javascript talking to Chimera over the latter's REST server. The first few 'list models' commands work fine, but when I send a command 'open cifID:4zhp' I (usually but not always) get an error '[Errno 32] Broken Pipe' in Chimera. Is there a clue in the stack traces below as to the reason for this? Thanks. Chimera 1.12 (build 41481) on OSX Sierra 10.12.6.
