Logout ui is off center

I realize this is somewhat trivial, and I would let it go except the same problem exists in edgy as it did in dapper and I had reported it about dapper as well.
The logout dialog UI is off center, down and to the right.
 I would appreciate it if this were centered on the screen.
 If you guys will not do that perhaps you can inform us as to the location of the file that will allow each user to center, or move, the logout dialog ui themselves.
