Auto show a download dialog box?

Hey,

I am building a download site, and when users click a link to a file i want a new page to open wich shows some explanations, and automatically launches the download (shows the open / save dialog)

Ive got it working, but on IE it does not show a file save dialog, but just the security bar on the top, how can i make IE show a save dialog box?

Regards

The IE security seems to be doing its job.

When you trigger the download, about the only viable solution is to advise the user about the yellow bar, telling them to click on it when it appears.
When the user initiates the action, such as on a button click, it should not appear.
