The related links block does not show on all node types it's supposed to.

Hey there,

I use the related links block for a certain node type, and I wanted to add the same functionnality for another node type. I selected the second node type in the related links settings page, but I don't see the block show up on the new content type page I selected... is there anything special to do to hav that block show on several node types at the same time?
Thanks,
Patchak
