i know that you set up scrolling in a frame through the properties inspector
but can't see how for an iframe. when i select my iframe (in the receiving
template plate) i don't even have scroll as an option to set within the props
inspector. http://www.demhdevelopment.com/htms/my_listings.htm is an example.
does the inserted content need to be a frameset or can it just be a regular
basic page? would the scrolling be defined there instead?:embarrassment;

If I am not mistaken, and if I understand your question, I believe you can set
it up through the HTML.
Example:

<iframe src="iframe-source.html" scrolling="no" frameborder="0"</iframe>

Just change the scrolling to equal yes.
