My Mac runs Poser with some quirks that I just ignore. The image export icon has it's tiling set to u 0.5, v 0.5; spinning dials don't work until I click into the field, punch in a number THEN spin the dial. I don't spend much time in Poser so I personally don't care, even though I didn't have these issues in Windows.

On the other hand, the Mac experience has been blissful, and I'm required to make my standard "Mac is running UNIX underneath the GUI" comment.
