Bug Description

To reproduce:

1. Have two monitors
2. Maximize a window on one monitor.
3. While the window is activated, click in the top left corner of the other monitor.

This sends a close event to the active window, on the other monitor. The close controls are not shown, so it is possible to do this by accident. For example, if out of habit you click where the BFB used to be in natty, you can close the window on monitor two by accident.

Here is a screenshot explaining the problem, hope fully it is easier to understand.

BTW, it works both ways. Clicking in the top left corner of any monitor closes the active window regardless of which monitor it is on.

This even works if there is no maximized window on the other monitor. So the panel-looking-thing that is not a gnome-panel (and I sometimes wish it was) is at fault. No other window needs to be involved on the monitor where the click is done.

Ah yes, you don't need a maximized window on both monitors. That was just a coincidence.
