Probably less time, if you get rid of those common blocks. :-)
This error occurs when you try to add the same
object to more than one object hierarchy. For
example, you can generate the error by creating
an image object and trying to add the image object
to two different model objects. The idea (I think)
is that as you build an object hierarchy, each
object can have many children, but only one parent.
That is, there is only one connection from an object
in the UP direction in the hierarchy.

Uh, I don't do code. Particularly this *much* code! :-)

Hehe, I'll learn someday to get rid of em...
But as I read the (usefull) block of code, to me it seems like I'm adding
multiple image objects to one model... which seems to me like many
children to one parent.
FOR i=0, nb-1 DO BEGIN
oImage[i] -> SetProperty, DATA=image[*,*,i] ;where image is a 3d array
oImageModel -> Add, oImage[i]
END
oImageView -> Add, oImageModel
