Frame Buffer Background issue

[Streetwise]

When I look at an IPR with the Background set to a white .jpg, the window lights up as expected. But then when I hit Render, all of the sudden one of the props grabs onto the background color and I can toggle it on/off. What the heck is going on?

Could you strip down the scene and send it so we can take a look? Mention me and include a link to this thread.
