From the code, it looks like blue boxes are compound objects, red boxes 
are lone objects.

You have 3 frame level objects and the default +MB setting, and still 
get bounding slabs?
The default is 25, and the number considered is the number of frame 
level objects. In fact, whether or not to build the slabs is decided 
right after printing that information, in Build_Bounding_Slabs() in 
bbox.cpp. The code's a little odd, but should work as expected. Maybe 
there's an .ini file setting or something overriding the default...
