Newbie Tkinter problem

[Simpa]

Hi.

When I start the following script twice, without leaving Python I got
TclError message (first time everything is OK). What am I doing wrong?

I am using Python 1.5.2 for Win32 with Mark Hammond's PyWin, but same
things happend on IDLE too.

Thanks in advance.
Simpa.




from Tkinter import *

class Wind:
    def __init__(self):
        self.root = Tk()
        self.root.title('Show image')
        
        self.c = Canvas(self.root,background = 'green')
        self.photo = PhotoImage(name = 'wedda',file="wedda.gif")
        self.c.create_image(0,0,image=self.photo,anchor=NW)
        self.c.pack(fill=BOTH,expand=1)

        self.root.mainloop()

MyWind = Wind()
