object shows only wrong when attached

Hello there,

I have made an object which consist of several boxes in a grid, exacly alligned to eachother. If I have rezzed it normal, it shows okay. But when I attach the same object to my avatar, the rendering isn't quite right: boxes that lies behind other boxes are rendered before them!! All persons in SL see that happen, so it's not my client which is corrupt or something.
See attachments for an example.

Does anybody knows how to solve this?

Many Thanks!

from the partial picture it looks like the alpha sorting bug if ya can put a solid prim between them but from the pics i cant tell what you got there

Thanks Lightwave Valkyrie, it is apparently a know bug. I hope they will fix it soon!
