Furniture Objects Appearing Black in 3D View

[spes]

Hello, I am a new user (just started yesterday) so the solution to this problem may be obvious to more seasoned users, but I cannot find an instance of it in the previous posts.

I am running Sweet Home 3D 1.2.1 (can you show me where I might download an update?) on Mac OS X 10.6.3. I am designing a 5 room office space, and when I place furniture objects anywhere in the design except for in the far right quadrant, the object appears black and monolithic in the 3D view. All of my interior walls also appear black (despite my selecting that they be white in the Modify Walls feature). Did I neglect to turn something on or off when laying out the design?

Thank you in advance for your assistance, and thank you for developing this fun and useful software.

Maybe you drew your plan in a zone where light isn't active, like Hans showed in this thread.
This bug is fixed and you should update your version of Sweet Home 3D with the latest one.
