OK... I tracked it down and found the 'P_NOWAIT' didn't work. I
replaced it with '1' (no quotes) and everything went fine on bot OSs.

The error message on Windows helped finding it out (it said that an
integer was expected but I got nothing on Linux).

It ended up like this:

   os.spawnv(1, 'c:/python22/pythonw.exe', ['c:/python22/pythonw.exe', 'another.py', parameter])


This avoided the need for threads on this program, thanks.


Just to make the solution complete, only the 'thread' module worked on
Windows. I couldn't get the 'threading' module to work there.



Thanks for all the help.
