(Ubuntu 13.10) Unity program menu (the one you get by hitting just ALT key by itself) always shows Chromium menu.

When the menu appears it has correct icon but the menu items are for Chromium (Reopen Closed Tab etc.) and if I type anything or scroll using arrow keys the icon also changes to Chromium icon.

This happens on a computer where I set focus to follow mouse. Not sure if it's related at all but on another computer where I have default focus (click) the ALT menu works fine (the other computer is also Ubuntu 13.10).

Any ideas what's wrong and how to troubleshoot this?

Thanks!
