Why does Firefox and Chrome ONLY load Flash when it comes into view?

I’ve struggled with this a lot

Flash will ONLY load when it becomes into view on the screen
For example, it won’t load a Flashmove that is at the bottom of the page
INSTEAD: it will ONLY load when that part of the screen comes into view

I think I’ve sussed out characteristics:

  • Older Flash, ver 7 and below, this isn’t a problem

  • Newer Flash, ver 8 and above: problem

BUT: this is NOT a problem on IE

Why why why!
How can I control and MAKE load?
