Carousel menu...once again

Hi i am working on a modified version of the gotoandlearn xml carousel menu and i would like to add a stationary logo in the middle.
If i just place a MC in the middle of the stage it won’t work because the icons go right through because the carousel is the the highest depth, also when i click on one and load my external swf the MC in the middle just stays in the middle of the page.
How do i place the object in the middle at the same depth of the icons and make it disappear(_alpha function?) when i load the external swf with the xml?
Does it have to be loaded with the xml or could it be just place there in the middle of the carousel?
Thanks
Mas
