Paul Prescod said: "Tkinter code is not compatible with the PythonWin environment. You should use Komodo for that." Paul, Could you please elaborate on this incompatability and be more specific. I have just started using Pmw and tkinter in pythonwin over the last few days and have not seen any compatability problems. But my use of megawidgets has been limited, so I would like to know about possible problems. Also, does IDLE have whatever these problems are too?
