I'm guessing that's what it is. I reinstalled Ubuntu and replaced my newly created home directory with my old home directory. Problem is, my new Ubuntu doesn't have XYZ program installed and when I double click a file it attempts to open it with XYZ program. How do I 'reset' my home partition so that it won't use non-existent programs?
Specifically, its WINE. It wants me to open files with internet explorer and notepad.
