UE 3 Rookie dynamic shadows question

I have a spotlight casting onto a a set of doors (Movers). The floor is made of a series of static meshes. The only light that should be shining into the hallway pictured below should be a small sliver since the doors are ajar. Instead I get that.

The shadows continue coming out wrong even after trying several of the suggestions listed on the Epic forums and I'm a bit stumped at this point. Anyone here know how to fix this?

Thanks for the info, KungFu. I've been playing around with it using your suggestions, but it still appears to be doing it's own thing. Using dynamic shadows just shows these crappy box shadows around the base of the doors. Once I get a chance, I'll post some screenshots of what it's doing. I'm starting to think the GoW version of the Unreal 3 engine might not support dynamic shadows.
