How do I force the download dialog box to appear in IE6 (maybe other versions) when downloading a ".dwg file" from my .aspx page. The downloads themselves are working - but no dialog box. IE7 and Firefox however work fine. I have tried placing a Content-disposition: statement onto the page but this seems to work only for a specified file (also I suspect I did not structure it properly). I have many .dwg files on the page and need the download dialog box to appear every time any of them are clicked.
