I have noticed a very odd thing a couple of weeks ago regarding this bug that I still have like many other users I presume (as a side note, I still experience live games freezing when using IE and unexpected log outs while exploring the BB world) and since you have not found how to fix it, I will post my observation here.
I can't see the prefered position in any roster page, mine or others except on NTs roster page where the PP fits perfectly well.
