I have an ASP.NET 1.1 application that uses the following code to write out a file in the response:

```
Dim objStream As Object
objStream = Server.CreateObject("ADODB.Stream")
objStream.open()
objStream.type = 1
objStream.loadfromfile(localfile)
Response.BinaryWrite(objStream.read)

```

This code is called by a pop up window that displays this file or gives a open/save dialog in Internet Explorer. The problem is, that it seems to work fine in IE6 but in IE7 the pop up opens and then closes without displaying the file. Any one know whats wrong?
