Ah I see, so it didnt disappear, it just takes long to get the polygons reduced then, well if that is the case then I guess I will let it do its thing. I didnt really think about it bevause well what I expected was that once I drop it under the polygon reduction, it will freeze the whple program while the objects polygons are being reduced, instead what I got was that the object just disappeared and all other functions were working as fast as they used to.
