Hello.

@rottweiler,

I suggest you contact the Unity QA team if indeed this is a bug. This sounds like something that’s specific to your machine, so we aren’t going to be able to reproduce it. I also suggest looking into lightmapping your objects in an external program, like Maya or Blender, and bringing the lightmapped objects into Unity. There are a number of tutorials for this, for example: http://forum.unity3d.com/threads/8998-Making-lightmaps-in-Maya-(tutorial)
