Martin (or anybody else),

The problem with FTYPE is solved.

However, after having switched to py 3.1 with the help of the BAT
script (which only changes FTYPE) I have another problem.

(Just for reference, here is my batch file)

ECHO ************************************************
ECHO Cambia a Python 3.1
ECHO ************************************************
ECHO .py=Python.File
ECHO .pyc=Python.CompiledFile
ECHO .pyo=Python.CompiledFile
ECHO .pys=pysFile
ECHO .pyw=Python.NoConFile
ECHO ************************************************
FTYPE python.file="C:\Python31\python.exe" "%%1" %%*
FTYPE python.compiledfile="C:\Python31\python.exe" "%%1" %%*
FTYPE python.NoConFile="C:\Python31\pythonw.exe" "%%1" %%*

The problem is that, if I am on top of a .py file, and, with the
mouse, I click on the right button, then I click on "Edit with IDLE",
I get the 2.6 system, not the 3.1 one (which was supposed to be the
correct one after the change).

My question is: are there any other changes that I should do in order
to fully switch from one version to another?

Thank you in advance.
