My (admittedly weak) understanding is that an application can either use the operating system's native controls, or it can opt for custom-drawn controls. The former should be more accessible as the OS knows how to expose them, while the latter gives the developer more control over the appearance. However, it also means that, unless the developer takes the pains to make those custom controls accessible, they won't be. And in my experience, very few Flash developers actually take that time, not even to get basic things down like the scroll-wheel, let alone more obscure things like accessibility.
Signed, a Flash-hater.
