hey ,
I figured out that when I am using "instmodsh" command to get the list of the modules installed I am getting the "Tk module among the list of installed modules. Now i dont know why I am getting the same error for each program I am running using the Tk module. I f the Tk module is handsomely installed then it should not give any kind of such errors.
Please help me out I am stuck in it from a long time thanks in advance.
