Two relatively small problems with Poser Pro 11 that I have encountered:

1. In the Library, in the Tree tab, the slider to adjust the size of thumbnails works, but Poser doesn't "remember" the setting from session to session, so I have to reset thumbnail sizes for every folder every time. Mildly annoying.

2. There used to be a helpful little "loading" indicator when you were loading a pose or a figure or whatever...it seems to be gone. I found it useful and miss it.
