File not found ??

[Suma]

Hi,
I recently downloaded TextPad.
I also changed the associated application for .java file types to TextPad.
But if I try to open a .java file from explorer, I get the error message that says
"Cannot find c:\test.java"(or one of its components). Make sure the path and filenames are correct and that all required libraries are available.",
even though the file opens CORRECTLY in a textpad window !!. How do I get rid of this problem ? Any help will be greatly appreciated !!
Thanks you,
Suma.
P.S: The platform is windows 2000
