Although the Yahoo! Floating Cart is considered pretty much bug free by Yahoo (you can look at the official open issues list here http://help.yahoo.com/l/us/yahoo/smallbusiness/store/floatingcart/floatingcart-09.html ) , there are some pretty "interesting" issues still, so since I keep running into them, I decided to post them here along with the work-arounds.

Nothing else works currently. 2) If you have a script that checks if the shopper made a selection from a drop-down (basically, any kind of an "onsubmit" handler), the floating cart will still receive the item, even if you cancel the submit event. The workaround: put the event handler on the click
