Links and form can make use of target attribute; not iframe:
http://www.w3.org/TR/html4/present/frames.html#edef-IFRAME

The overlapping behavior issue may be caused by something else and has no relevance to target.

The <iframe> is declared first in the source code before the rest of the content appearing on the left. So, it looks normal and reasonable that there is an overlap from the rest of the content when browser window viewport is narrower. I checked with 3 other browsers (Internet Explorer 7, Opera 9.51, Safari 3.1.2) and this is also what they do (the form gets under the rest of content).

I'm afraid this behavior is normal and that NS 7.2 is wrong.

-----------

On an entirely different topic, the 3 framed and frameset webpages could use an upgrade.

The markup code in all 3 framed and frameset-ed webpages is very "tag-soup", relying on deprecated attributes, using incorrect doctype declaration and with dozens and dozens of validation markup errors.

If you want to upgrade your webpage code, then I suggest

target and target="_top" have nothing, absolutely nothing to do with stacking levels and stacking order or z-index-ing of elements of a webpages.
As far as I can see, the overlapping of the iframed form when browser window viewport is narrower is the normal behavior here.

Resolving as INVALID
