I don’t, sorry. I’m testing JigoShop right now, very powerfull and easy to use.
Same way for me. Clean install with WP 3.2.1, TwentyEleven and without any installed plugins.
When I activate wp e-commerce, media library, add tags, html view and other user-friendly stuff doesn’t work at all. Obviously, everything works without WP E-commerce. I think I have jQuery conflicts in fact.
