I think that Macromedia is a smart company. If they actually act on the feedback then they just created a free usability test with thousands of participants. Very smart.
We are aware of the issues with Safari and Opera browsers, and are actively working with Apple and Opera to resolve these issues. We hope to report on progress soon.
If only I could call up Apple and get them to release another Beta of Safari because my site doesn't render quite right...
