I am creating a web application using C#.  I have a login page that is
used authenticate the user and redirect them to another web page called
Run.aspx that runs an executable that takes their username as a
parameter.  Currently I am using Response.Redirect(Run.aspx) to take
the authenticated user to the page.
Session ["UserName"] = userName.Text;
System.Web.Security.FormsAuthentication.RedirectFromLoginPage(userName.Text,
false);
Response.Redirect("Run.aspx");
Now I need to take the authenticated user to the page by opening a new
window.  I have read most of the post concerning this subject and tried
the suggestions, but  I can't open a new window.  I have tried
something like this:
string script = "<script language='javascript'>window.open('Run.aspx',
'_blank');</script>";
Page.RegisterStartupScript("script", script);
and others, but nothing seems to work.  I would really appreciate any
help, thanks.
