<blockquote>>>I ask my students to use the homework folders to pass back their results. When they upload the content dotlrn seems to store the file into a file named "index" loosing the document specific extension. This is fine as long as a browser can deal with the content. But sometimes this is content which cannot be presented by a browser. When I download it (save link as ...) I just get a file named "index" (see above).

This part is fixed in the dotlrn-2-0 branch. The files are now downloaded with their orignal name. It will be in dotlrn-2-0-3.
Going to look at the patch for the details link now.
