I am running Windows 7 with an i7 and 16MB of RAM. My nVidia chip has 2GB memory.
I created a new LandscapeMountain project, started the lights to build, switched back to the launcher and then everything locked. solid.
Only the mouse could move. I could not switch windows, and no keys did anything.
I can’t remember anything causing this level of lockup with any of my Windows 7 work. This is serious.
Based on no actual facts, I think there is something wrong in the lighting calculations.
I am going to try it again. I bet nothing happens this time.
