Didn't know where to put this question or how to search for it in the forums so if it is a duplicate I apologize. I just installed LinuxMint 13, was running the update manager, and getting everything set up the way I wanted it when I noticed that my bottom bar went missing. I have no idea what happened to it and didn't get any error message. The only way I have of navigating through the apps, etc that I have currently open it to Alt+Tab through them. How do I get my bottom panel back?
