List posts from specific combination of categories

Hi,

the plugin is wonderful, however it lacks the following function:
– example – we have many posts that are listed under many categories – post 1 is listed under cat 1,2,3 and post 2 is listed under cat 1,2,4 and post 3 is listed under cat 1,4,5
– we need to list posts that are listed under category 1 and category 4 ONLY
– the output should be ONLY:
Post 2
Post 3

How can we do this?
