Hide the related posts area in post and page edition (YARPP)


I'm using YARPP on my network.
I'd like to hide the YARPP related posts area which is on every post and page, when you want to edit it.
Any (simple) idea?
Without a plugin if possible...

Best Regards

PS:I tried Adminimize (plugin) for things like that but I'd prefer to avoir using it because I encountered some conflicts.
