It actually is a little different because Flash is a plugin that has to first capture inputs. In order to interact with Flash content you first have to click it so that it can capture the pointer input. Then you have to interact with the content. Then you have to be able to tell Flash to release the pointer so you can move throughout the rest of the page. But if you double-click should it zoom in, capture those inputs in Flash, or zoom out?

This man speaks the truth!
