[Tutor] Tkinter wierdness

[Isaac Hall]

I was wondering if someone could explain the source of some wierdness I am 
seeing in Tkinter.
I have a program with a main window, and later create other Toplevel 
Windows.  I place a button in the Toplevel window, but then the wierdness 
ensues.  the command for the button is run when the button is created, and 
can never be run again!  clicking the button afterward does nothing.  can 
someone explain why this is happening, because I am stumped.  

Thanks

Ike
