Navigation and .mht - how to manage

[huzzlepuzzle]

Hi there,

I've created a bunch of .mht documents that are all linked together using
hyperlinks. I store them all in the same folder.

Some of the .mht are key menu and there is a hierarchy thatc an be followed.
Problem is that users can get lost jumping from one document to the next.
is there some way of putting some navigation map which appears on each on the
..mht which they can use to get back to key hierarchal .mht's??

Also - if they hit the close button they lose the lot - how can i disable
the close button specific .mht docs?

Thanks for any advice
