Slide Show Error.

I am using Windows Vista home premium on an MSI media centre. I am running
all my media of an external Terra bit drive in directories for music, video
and pictures and its now all working ok except..

When i use media center to play Music albums and run the photo slide show at
the the same time it plays my expected photo's but also plays the music album
covers as photo's in the slide show. Also when i tell it to stop watching a
folder location it still remebers it. Any idea's greatfully received.
