You may be having one of these issues:
1. Are you in single-window mode? You can check by going to the menu bar:
Windows -> Single Window Mode.
a) if you are, you can open any of the dockable dialogs by going to the
menu bar again: Windows -> Dockable Dialogs. Then just choose the ones you

b) if you are not, are the dialogs off-screen somewhere? Try going into
Single Window mode, and see if your dialogs appear on the sides of your
