After upgrading to 12.04 and being on Unity, I am having this strange problem.
Say I have opened a few apps, e.g., Chrome, GNUCash, GIMP, etc., and I am presently working on GNUCash. When I press Alt+Tab to switch some other app, the app I was working on, e.g., GNUCash simply hides somewhere and I cannot find it where it is. However, in System Monitor, it still shows up.
Can someone help me figure out where these apps are getting hidden upon switching to other app.
