I have a Google Chrome window that's unresponsive. It's a login window for a public WiFi network, and I have the spinning beach ball of death whenever I put my cursor over that window. I've been forced to move it to the bottom of the screen, because I can't close, minimize, or unfocus it. I looked in the Activity Monitor, expecting to see a Google Chrome Helper process listed as unresponsive, but there's nothing. What exactly is going on here, and how can I find the unresponsive process's PID so I can kill it? This is a situation that occasionally comes up in Mac OS X, and I would like to understand the reason for it, as well as the solution. Any help would be appreciated.
