how to put in its own window
There is two ways to do this. Once you have Panda Crazy running in a tab you can drag the tab away from the top of the browser window. It should automatically create a window with that one tab in it. You should just put it somewhere on your desktop and only work in the other window with all your other tabs. I like positioning it below my windows so I can see the queue watch on the side.
You can also click on the browser menu. It should have New Window at the top. Just click on that and it will start a new window for you. Load up Panda Crazy in that window and leave it in the background. I believe Ctrl+N might create a new window also.
