This is a known problem that when publishing to CMSCORM/SCORM/AICC/HTML to a zip file, the progress bar images are not included in the zip file. The images folder is left outside of the zip. Therefore, the images are missing once imported and this is why the progress bar does not display in CourseMill. This should get fixed in the next Lectora 2007 service pack update (SP2) - to be released around the end of the month. For now, when you publish to CourseMill, once the "Send Title" button becomes available, you should go out to the cmscorm/html publish directory, locate the images folder and place this inside of the zip file. Then click on the "Send Title" button. Now, the progress bar images should be there after import.
