Reproducibility: always Steps: 1. Go to http://www.testwebcam.com/ 2. Click on any button on the Flash security confirmation dialog. What happened: 2. Nothing. The buttons are not clickable. Expected result: 2. The buttons are clickable.
What build are you seeing this with? Is this shipping Safari/WebKit 5.1, or a nightly WebKit? What version of Flash?
The problem also occurs with public 5.1, not just nightly. I have Flash 11.0.1.60

This is actually a bug in Flash that will be fixed in a future Flash player update.
