:) I have always found that Moi has some difficulties speed with numerous objects :)
So happy that is resolved :)

Another question :)
In Google Sketchup when you "dupplicate" (or copy) an "objet component" (or an object "grouped") (say a box B) the result file size B + B is less than a simple box A + a simple box A
So when you have numerous same object's components or grouped : file is magically very small :)
example: a box B (grouped) * 100 = 44 kb
a simple box * 100 = 132 kb
Is it possible in Moi?
