Comment 2 for bug 598326

After playing around a little more, I think the reason for this is that TwinView doesn't allow windows to be drawn between screens at startup. I found that if I move the GnoMenu icon (which is the Ubuntu icon inside the gray ring) one space to the right in AWN, it draws where I would expect it. It looks like GnoMenu is trying to be drawn in the center, under its icon, but TwinView is shifting it to the left or the right, depending on how much of the menu is on each monitor.

The expected behavior would be to see which monitor the GnoMenu icon is on and adjust position accordingly.
