(v 1.7.0)
When using MARK EARLIEST I noticed that the mark cue was the cue after the one that brings the channel to zero, unless that cue was immediately preceeding the reference cue. This means another GO is required after the lamp fades to initiate marking, potentially wasting a lot of time. If noise is an issue requiring long mark times, this is an important point.
It also will not mark the first cue in the list if there is a hard (blue colored) zero in the intensity column.
This is not how it is supposed to work according to the manual pdf on page 193.
