If one opens the tour guide window and just selects "goto", nothing happens: it doesn't take you to Jupiter.
If you highlight the Jupiter entry, and then "goto, nothing happens.
However, if you highlight some other destination (e.g. Pluto and Charon), then highlight Jupiter, and then select "goto", it goes to Jupiter..
This same bug is present in v1.2.4.
