The leaning issue (at least on mine) was due to the base pad on the right side being flattened. I replaced the pads with plastic ones from Wal-Mart and my leaning disappeared.
The "leaning" was so subtle that I only noticed it when I got my new Besta cabinet.
Just wanted to echo this. Had a look at mine yesterday, and the pad on the cap side was getting crushed. It was causing the base to lean at an angle. Mine is otherwise fine, but I can see how if you have warm temps, a bad base, etc, this could contribute to a problem. I don't move mine either. Have since added a pad and am not worried, but everyone should check. Also, I had to wait and wait for mine, so anyone who got theirs first may have had this going on awhile now.
