I'll stick to Python2.3 with this project, just in case until I get =20=
something working.

Thanks for the suggestion. I'll try some. I did try to put some =20
printfs in the ProcOn() code but I couldn't see them through the =20
python interpreter. (I've got rusty C and almost no C++ chops)
Would you be kind enough to show me a quick-'n-dirty simple eg of =20
arguments to SndJackIO?
many thanks - unfortunately I've got two other build in progress with =20=
different types of problems..
very dry, creatively - one needs the patience of an animator in =20
these situations!

*If you like TV tennis (my 1 TV sport indulge) the Aust. Open Men's =20
final (Federer vs Gonzalez)
is today (16h00 here =BF=3DGMT+ 5?) and promises to be an extraordinary =20=
display.
They've both completely dominated their prev. opposition with =20
balletic performances.
