Yes, you are right! With an ending "/" it works.
See the difference to OpenFile and SaveFile dialogs.
i use gb.form.dialog component.

----------------------------
Public Sub btnOpenFile_Click()

  Dialog.Filter = ["*.txt", "Text Files"]
  Dialog.Path = Application.Path
  If Dialog.OpenFile() Then Return ---> wenn falsch (Cancel gedrückt = falsch??), dann RETURN?
  txtArea.Text = File.Load(Dialog.Path)

End

Public Sub btnSaveFile_Click()

  Dialog.Filter = ["*.txt", "Text Files"]
  Dialog.Path = Application.Path & "/"
  If Dialog.SaveFile() Then Return
  File.Save(Dialog.Path, txtArea.Text)

End
----------------------------

SaveFile works with
  Dialog.Path = Application.Path & "/"

OpenFile works with
  Dialog.Path = Application.Path

Benoit i think this is a small bug.

..........


Not at all, it is a bug in the container arrangement routine that shows up
only with gb.gtk.

It is fixed in revision #4182.
