Application.OpenConfigWindow -- show MUI preferences window
Synopsis
mui.DoMethod(id, "OpenConfigWindow")
Function
Since MUI 3, applications can open their own MUI configuration
window to allow users to adjust the local preferences without
the need of an external program. Programmers are supposed to
include a "Settings/MUI..." menu item which simply calls
Application.OpenConfigWindow. MUI will then automatically
show the preferences window without blocking the rest of the
program.
