You can fix seems a good number of ways. I try to UV unwrap so that the seam is running along a surface with a change of colour/texture or possibly a sharp edge, so it's harder to notice. If this isn't possible, there's always the option of going into texture paint mode and doing a bit of blending to remove the seam. If you go to blendercookie.com they have many tutorials on texturing

Did you try placing the 3d cursor on the texture you want to clone?

*shrugs* I can't fix seams either (well I can through workarounds, they just take time) so I just try to make sure the UVW map is laid out in a way where seams are kept to a minimum and in places where they won't be seen ^^"
