Easily verifiable. Avatars are hovering over the sit object. Depending on the object size, the avatar may hover just over the object (cube). On large objects the range increases with the prim size and the avatar may have it's head in the clouds on sit.

Here is not relation with object size because the size of this object is small.It is also far from the clouds.

when a avatar is sitting on a box,his BUTT of the avatar's body should touch the side of this box as same as the pose when sitting on a ground.But,now he just seems sitting on a desk.

Can confirm. This also happens when sitting on a normal 0.5 x 0.5 x 0.5 box. Also don't forget other prim types too, such as cylinders, spheres, etc... look in my attachment what happens when I sit on a sphere.

Still happens in rev 6880 when creating a sphere and sitting on it. Opensim attempts to sit the avatar accordingly to the sphere's rotation on the top of the sphere, so if the prim is rotated it sits you wherever it faces at considering that's the top of the prim you must sit on. A correct implementation would be to sit on the real / current top of the sphere that is the most upper part, no matter how it's oriented or rotated. Of course unless there's a llSetSitTarget script in the prim.

In 0.7.2-dev, sitting position has been almost fixed, but still avatar sits on the air above the box.
