When doing a structured Panorama with a lot of pictures (1800) sometimes the enumeration of the pictures in the camera restarts after 9999 at 1. That leads to a set of pictures for the pano starting at DSC_9000.jpg to DSC_0800.jpg. ICE sorts the
pictures by name and not by date of "picture taken". I always have to rename the pictures
On Windows Vista,7,8 ICE imports the images into structured panorama in whatever order they were sorted when you selected them. In the file selection dialog you can change the sort order to anything Windows allows "Name", "Date taken", "Date modified",
... and ICE will maintain this order when populating the structured panorama grid.
