Question

function SendInfo(href) {
    var subject= "Some information";
    var body = "I thought you might find this information interesting:\r\n\r\n<";
    body += document.location;
    body += ">";
    var uri = "mailto:?subject=";
    uri += encodeURIComponent(subject);
    uri += "&body=";
    uri += encodeURIComponent(body);
    win = window.open(uri);
    win.close();
}

In FF, Chrome and IE9, the new tab/window closes as it should.

However in IE8 and below, a new window opens and the user gets a security warning.

Is there a better way to approach this to prevent those issues?

It is not optimal to open a window that you need to close.
If you did not get a warning you could use setTimeout like this:

win = window.open(uri);
setTimeout(function() { win.close();},1000);

Instead I suggest you do this

function SendInfo(href) {
  var subject= "Some information";
  var body = "I thought you might find this information interesting:\r\n\r\n<";
  body += href; // or document.location;
  body += ">";
  var uri = "mailto:?subject=";
  uri += encodeURIComponent(subject);
  uri += "&body=";
  uri += encodeURIComponent(body);
  return uri;
}

<a href="#" onclick="this.href=SendInfo(location.href)">Tell a friend</a>
