Viewing Files within browser window

Hi,

When users have their browsers setup to automatically open word or pdfs within their browser, the file name is not transfered, instead the fid is used. This means if they try to save a copy of the file it's called 4.doc (or similar). Is there a way to pass the file name instead? This works fine if you right click and then open the file.

I'm trying to get a consistent view and/or download process for a number of non-technical users who mainly use IE6. I've had the same issues as http://drupal.org/node/244852 and implemented the "fix" for IE:

1632-1686 in webfm.js
// Not an image - launch file in new browser instance
if(!sent) {
// window.open (url);
window.location= url;
}

Now they can open the files within their browser but are struggling with the naming....Help
