Setting the content disposition to 'inline' instead of 'attachment' causes the document to be loaded in the _blank window. The documents being downloaded from this form can run quite large. Loading them in the window could take a while, with no significant feedback being sent to the user.
This is why the client is asking for the "save as" dialog box to appear when the form is submitted. I used to have a link set up so that the user can simply right-click and save the target. Instructions were even posted on how to do this. But it seems their users cannot figure this out, so they asked for the "save as" box to come up programmatically.
Which leaves me back to my original problem of a open, unused window blocking the focus of the parent window....
Thanks,
