I thought it was going to be something like that. My work around, because it appears that the problem has a lot to do with whether IE thinks you specifically requested the download or not, is to put a link on the page where the report is created, rather than attempting to do a window.open(); when the operator clicks on the link, IE recognizes that you asked for it and behaves as we would expect and offers to Open, Save or Cancel. We just can't do it automatically any more.

Thanks again,

That's really an IE 7 issue - it blocks access to any files that open applications that potentially run script code (as all office apps do)...

I don't think there's a way to override this though - you can change the Mime type settings of the format though I believe. Find a file with the .csv extension and and right click on properties. There should be an option page somewhere that allows you to select what app opens it and whether there is prompting or not.

Note that it 'll also help if you provide an explicit Content Type type in your output of the file.

More on this:

It is indeed a security issue. If I navigate to a webpage first and then refresh that page and redirect to the csv file, Vista puts up a bar at the top of the browser saying "download has been blocked, click here etc." and at least you get to click there and accept the download. But I could not find a setting in Internet Options Security settings to avoid this hassle.

What a pain!
