When editing an attachment and choosing the normal or specular map, the texture picker popup does not scroll to and select the texture in inventory. Editing the object when unattached or choosing the diffuse texture when attached works as expected. I tested this by just creating a cube (attaching to right hand) and setting its textures from my inventory to some Linden Home textures (diffuse, normal, specular), which are full perm. I cannot say when this might have changed as I don't edit attached objects very often.
