Hi Guys. I'm going to whisper you a link to a screencast I made, which shows some strange cart behavior in Safari, on one of my client's sites.
Here's what's happening in the screencast:
* Page is loaded
* Item is added to cart
* Cart slides in, then disappears suddenly, without being dismissed by user
* Page is refreshed
* Cart appears for a split second on its own, unprompted, then disappears again without being dismissed
* Page is refreshed, and everything is back to normal
This sequence can be repeated every time I add something to the cart. No errors are coming up in the console. I don't have another 2.0 site to compare it to (that I can think of), but this happens on both the live and dev site.
