Export scripted behaviour doesn't work for me either. Or rather, even if I export the scripted behaviour, after restarting RB, my scripted behaviours will become unrecognised.

I do see my scripted behaviours in ~/Library/Application Support/Remote Buddy/Behaviours/ - I also see the Camino and Google Video Player files. Those other two scripted behaviours are recognised but not the ones I make. Using RC1.
