Thanks for the BTC, but the kind of problem that I was describing is a kind of attack on users running firefox and chrome browsers: I can make them not have buttons in a first-to-act situation every time.
In other words, I'm running an opera browser, and "stealing" the small blind of a user who is waiting at a table is very easy. The browser featured on screen in the video is firefox, I make the firefox browser have no buttons by running opera on a separate computer.
I'm sure I can make the first person to act in a full ring game that is already running not have buttons just by sitting down with an opera browser.
