There is a drop down menu to select currency. Let's say I want to select TWD (New Taiwan Dollar), it's "below the fold" so I've got to scroll down. I do this using the scroll wheel, which I use almost all the time. So I see it's near the bottom of the list (because TWD starts with a T which is likely to be at the bottom of an alphabetically sorted list) and do a quick flick downwards. However rather than going to the bottom of the list, the list suddenly disappears and I'm no longer able to select my currency! Unless I can scroll almost exactly the amount I need to, either the TWD option is not visible on the list or the list closes. Even if I scroll slowly there is still a large chance I have to try a couple of times before I'm able to select TWD.
It looks like when you scroll past the bottom, an instruction to close the list is triggered, and then the window containing the page scrolls down. I think that's the problem which can be fixed by preventing the drop down passing focus back to the window.
