        I too have noticed the same problem.  Attached is a rollout of a
nack position that illustrates the issue.


Chase,

Your screen-shot looks normal to me. Plays in the rollout window are not
sorted after every trial, so you often get them in the wrong order while
the rollout is in progress. When the rollout finishes and you OK the
wondow, they results do get sorted for the analyssi display. Is this
what you observed?

Chris,

You situation looks more unusual. Is this a copy from the analysis
screen of a completed rollout? If so, it looks like there is a problem.
The only time I have seen this before is when I have rolled out the
plays one-by-one in the CLI, rather than select them all and roll them
out simultaneously from the GUI. Can you confirm exactly what you did,
please?

Finally, readers of this mailing list much prefer that you post in plain
text, rather than HTML.

Cheers,
Ian
