Yeah, the only way I can get it to work on a Mac is if I alt+tab twice. For example, Flash does this on my PC. If I hit tab, it will cycle through the UI elements of a Flash video. On YouTube, if I click the "play" button, then tab, it will highlight various components of the Flash player. I can't open a new tab unless I alt+tab twice, or unless manually clicking on the window (somewhere in a non-flash area). This isn't the case on Mac, but I find myself randomly losing focus of the browser window. Kind of weird.
