At this point in time we are not sure why, it seems to be a problem with Internet Explorer. The report creates jpeg images of the folder usage pie chart as well as the file and folder icons in a sub-folder of the main report page called 'reportname_images' (where report name is the file name of the report) and this sub folder forms part of the path used by the image tags in the html report.

The html syntax of the report is correct (Internet Explorer successfully displays the pie chart) and it should work, as indeed it does if viewed in other web browsers. The report will display correctly in Internet Explorer when viewed from a web server which, indicates the problem is related to the file: protocol used by Internet Explorer.

The progress bar displayed while a drive is being scanned is a rough indication achieved by comparing the used drive pace to the total size of all files scanned so far. Because it takes just as long to scan a large file as a small one, folders with lots of small files appear to progress far more slowly than those containing mainly large files.

The progress bar will often get to 80% or 90% and then appear to slow down when the scanning process hits the c:\windows folder which contains a plethora of small files, often disproportionately so when compared to the rest of the disk space usage.
