Pivot deforming problem

Hi I have a problem.... and that problem is shown in all most all of my projects.... its about liking and pivot points.... I have notices that when I used link option and link some object to another and try rotate my object starts deforming.... squashing and stretching.... so can some one tell me where am I going wrong?

interesting problem i tried this with some primitive boxes and it
worked fine I'm using 3dmax 9 maybe you are linking an object
while still in edit mode like when some polygons are still selected
when you link the object good luck my friend...
