Has 6.5.1 (or maybe jut 6.5x period) changed the way it handles avatar display over previous versions? On the live (6.4.x) version of my site, avatars that are larger than the specified dimensions (75x75) are forced to be dynamically resized in the HTML. 6.5.1 seems to be displaying them without resizing them, which means any over-size avatar screws up the uniform look of the post pages.
