Thanks. That was it.  I had switched it from union to merge; I was 
getting weird coincidence errors on the main outer box. They've gone 
away too.
(I think I was doing union {box {color Red} box {color Red}} instead of 
union {box {} box {} color Red}
)

Weird that merge has that issue. I would think it shouldn't matter for 
this application, just be slower.
