anchor with target="_blank" inside iframe sometimes doesn't work in internet explorer 8
===

i have an iframe with the following doctype:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

inside this iframe, there is an anchor whose `target="_blank"`

i got complains that when opened in internet explorer 8, sometimes the url is opened in that iframe itself (so, as if there were no target attribute)

and the questions are:

 1. does it have anything to do with my doctype?
 2. if it does, how to fix it?

thank you
