[1575] Recipients field in composer - mouse click not working

[exa-crw]

Observed in Firefox 2.0.0.14 and Internet Explorer 7.

The feature of showing a drop-down of matching names and addresses from the Address Book is only partially working.

Clicking an entry in said drop-down with the mouse results in a no-op. No error shows in Firefox's console.

It's still possible to select an entry with the arrow and tab keys however, suggesting there's something up with the click code.
