In fact, the two windows you created are not dialogs; they're just
windows. To turn a window into an actual "dialog", i.e basically to make
it modal, you have to do the following operations (supposing your dialog
window is named dlg and your main window in named root):
## Ensure only window can receive user events
## Force Dialog to stay on top of main window
## Wait for dialog to be destroyed

This is not the way it works. In fact, what you did wrong is something
that has been around for years in some Tkinter tutorial(s): you made your
classes inherit from Frame. This is a Bad Idea: a Frame is not a window,
but only a generic container. There are 2 classes for windows: Tk for the
main window and Toplevel for all others. They both also act as containers,
so you can do in them everything you do in Frames. So make your
ScriptDialog inherit from Tk, your SettingsDialog inherit from Toplevel,
remove all explicit creations of Tkinter.Tk or Tkinter.Toplevel and
instantiate your classes instead. Then calling destroy on either on the
dialogs will actually close the window.

This should work. BTW, your "done" method is not needed: creating the
Button with command=self.quit works without problem.
