so when you depress the left joystick it doesn't pause the game? Sure let me look at your config. Also do you have to install the XBCD drivers? The Microsoft ones seem to work fine for me except for the left joystick thing pausing the game.
I am having the same EXACT problem. I am using the Wireless Xbox 360 controller, windows vista. When I depress the left joystick it pauses the game....How do you get around this?
