The new notification tray has several problems with the dropbox notification icon right-click context menu:

1) If i open the tray by super-M or hot-corner then right-clicking on the dropbox icon does nothing.

2) In the overview, right-clicking on the icon exits overview mode and shows a menu. However, the placement of the menu is wrong, causing it to not be tall enough, forcing scrolling. It seems to me like it got the coordinates for the click being below the screen (just guessing).

3) If I open a notification using "zenity --notification --text=blah" and then mouse to the bubble and then to the corner to open the tray, then right-clicking on the dropbox icon *does* show the menu. However, it is positioned wrong in a different way. The menu has the full height, but it is placed one tray-height above the tray. The mouse input is in the "correct" place causing the highlighted menu item to be one tray-height above the mouse cursor.

4) Less problematic, but the context menu once visible is in the dimmed out layer with the other non-tray windows. It would be nice if any windows that have parents in the tray were not dimmed out.
