Loading pages in iframe

I am not sure if this is a WP general question or a plug-in question.
1. My WordPress site is setup as a Website.
2. I have a right hand sidebar and am using the dynamic sidebar plugin.
3. I have sidebars set up for each item on my navigation.
4. Each sidebar is made up of a varied combination of custom menus and widgets.
5. When you click on a widget item or menu item it displays content into an iframe.

Here is my problem… I have a custom menu called Services For Buyers – that has 7 menu items in it. This Custom Menu is on several sidebars associated with different top navigation pages. (Home, Buying, Community, About US) Unfortuantley when I click on the link it brings the correct content up, but brings up the sidebar for the default sidebar versus the sidebar for the page that the sidebar is on – let’s say buying. Is there a way to just have the content populate in the iframe without changing the page/sidebar? I want to be able to use the Custom Menu on several pages so I can go in and edit the Menu once instead of having to create it for each page and edit it 4 times…

Thanks,
