This menu mashing is a problem. This really has nothing to do with programing in Tcl, Tk, Python, or Tkinter. First of all, the "About Tcl & Tk" is hard-wired during the build of Aqua Tk. To fix this will require downloading the sources and building your own Aqua Tk from scratch: http://tcltkaqua.sourceforge.net/8.4.10/ Alternatively, you can res-edit the appropriate files. The "About Tcl & Tk" menu item is held in an rsrc file. I forget exactly where, but I can take a look on my ibook if you are interested in this route. To do this, you will want a working copy of resknife. I had some trouble with it, so I had to build it for my ibook with xcode--IIRC, the build I downloaded had problems saving. Getting the source and building on my computer fixed it. Its a great program. I'm guessing the best way to get around destroying your menus is to intercept calls to Tk(). I've had bad luck with multiple Tk() instances running in the same session (this is the case with EVERY implementation of Tkinter I've seen, Linux, Mac, etc.). StringVar and IntVar instances get very screwy with multiple Tk()s. You might want to re-define Tk() to return the root instance created by your program. Also, knew Toplevel()s will have their own menus, resulting in your application's menus becoming replaced while the Toplevel() is in the foreground, that's just how Aqua Tk works. This may be something you have to live with if you want your students (I'm guessing) to learn about python in your environment.
