Yes! I needed to Ungrab the pointer. I get prelighting on the menu items now, without releasing the mouse button, but I still can't make selections. I think this is due partly to some code in QuickListView that checks whether mouse presses are inside the quick list area.
How would I debug the Unity plugin? I found the following post (by you ;) ) which says how to start Compiz with gdb, but it looks like I'm restricted to compiz core. http://forum.compiz.org/viewtopic.php?t=11246 It might be that I just don't know how to use gdb very well! I've never used it with a project this complex before.
