It seems just to have started doing it by itself and I don't know how to restore the correct file association. Right-clicking and choosing "open with" is fine IF you know which app to choose. Should it be kdf? kdm? konqueror? And where are these likely to be located?
If I try to search for them, the found folders try to open with....AMAROK! So I'm a bit stuck. Any advice would be greatly appreciated.
