I’ve launched a new podcast series called Microsoft Conversations (podcast feed here). The first installment is a conversation with Chris Wilson about IE7, Ajax, and web standards.

Strategies for Internet citizens
Just a quick note about your file download with right mouse button problem: if you can set force outgoing Content-type: on file which you are serving to some unknown content-type (like application/download or probably more standard application/octet-stream), browsers will usually open download window instead of trying to display content.
Next thing, you will probably want to send correct filename, and one option is to use last path of url with correct name, But with few additional headers you can be really sure. Adding Content-Disposition: filename=$file (for IE5.5) or Content-Disposition: attachment; filename=$file and additional Content-Transfer-Encoding: binary will leave your users with just faint recollection about problems with download with right mouse button click :-)
