What steps will reproduce the problem?
1. onload
2. onmouse events (addEventListener('mouseover'  ...
3.

I've been modifying your helloworld example to experiment with svgweb.
It's weird. Flash rendering in IE is much faster when the background is 
specified than when it is not. Is that because of the transparency thing ?

What is the expected output? What do you see instead?

What version of the product are you using? 2010-08-10
On what operating system? Vista
browser: IE
and version of Flash? 10,0,12,36 installed

If you specify a background color, we set the Flash player to background 
opaque. If you don't, it gets set to transparent. Transparency is tricky with 
IE plugins because the plugin has to interact with the browser's layout engine 
more, leading to slower performance.

Marking this as WONTFIX since there is nothing we can do about the performance 
difference.
