Microcontent: block and menu contextual?

Please bear with me. I'm a newbie.

It looks like the microcontent module should allow the user to associate a microcontent node to a menu item and then assign that node to a block. The problem is that all the microcontent nodes are displaying in the block i assigned them to (in this case, the 'right sidebar') all of the time. I want a single microcontent node to display in that block when the menu it is assigned to is loaded.

For example, say my navigation consists of color>red>burgundy and i've assigned microcontent #1 to "burgundy" I only expect it to display in the sidebar when that link has been selected.

Am I misunderstanding how this module works?

Any advice is appreciated.

thanks,
