Bad interaction between indicator menus and compiz's expo

[pablomme]

Steps to reproduce (in both natty and oneiric):
- Enter expo mode
- Click on an indicator on the panel

The indicator will be highlighted as if the menu was open, but the menu itself does not display (see attached screenshot). On exiting expo and mousing over a different indicator from the one highlighted will open the menu without needing to click.

What should happen instead: either
- the indicators ignore clicks in expo mode
- on clicking an indicator in expo mode, expo mode terminates and the menu opens
- indicators display in expo mode (on top of the desktops, not inside their resized thumbnails, of course)

The second option sounds like the simplest and most sensible.
