I'd find this pretty annoying if it weren't optional--I hate the 'Are you sure? Are you really sure? Really, really sure?' approach.

I believe tye had some plans to make the consideration box look less like the chatterbox, which should reduce this problem. Right now it doesn't happen too often, and is quickly cleaned up. It's similar to /msh--a little embarrassing but not too serious.

As a temporary fix you might move your consideration nodelet and chatterbox far away from one another.
