If I place slides on the project then select all of them onto the time line then the published slide show is in the right order.
However if I change the order once placed on the time line or add a blank slide at the front as a title slide it runs in preview correctly but the published slide show is out of sequence. Title slide is at the end. The change of order seems to be ignored, slides are in original order.
I have reported it to NCH but no reply so far.
