Blender GE shadow error

I’ve been having a problem (in 2.58) with real time shadows, with some objects a shadow is produced, and with others, none. I don’t see any material differences between the objects that make shadows and the objects that don’t. Her’s a video:

Quick answer: Is your spot set to “Layer Only”, with the crate on a different layer?

Yes, that’s the problem. Thanks a lot!

Great. It’s good to organize your scene by object type, and it saves frame rate by setting lights to layer only, but of course you can end up with problems like that.
