I've was demonstrating the Auto Block feature to an Op. Everything worked as it should. A 'late' cue was revisited and updated with a change (ostensible putting in a Auto Block). An early cue was revisited and another change was made to that channel. In the Blind Spreadsheet (Oh what a tremendous tool this is!) we could see how the block prevented this tracking into and beyond the 'blocked' one. Good demo I thought until back in the PSD I did not see a "b" in there! What did I do wrong?
