I'm running Ubuntu 11.10 and using Unity. I have a bunch of applications open, including Empathy. When I hit alt+tab I can switch between all of the applications, and the "show desktop" option, but not Empathy. (When I'm alt+tabbing I don't see an icon for Empathy.) How can I alt+tab to Empathy?
(If I do shift+alt+up_arrow (Expo for current desktop) I can see Empathy and select it by clicking on it.)
