I'm not only having problems with the BIN button, but also with all other buttons. I'm no longer able to add to lists, see original listings, scroll through listing photos, enlarge listing photos. It all stopped working quite some weeks ago. Now, as of today, I can no longer read messages either. When I click on them, nothing happens as with all other functions, so I've essentially been unable to use ebay on my mac for some time now. This happened before, and ebay fixed it (it happens when they update their systems), but this time it's just not being addressed.
