thanks to all of you for your help - yes indeed I kept code at a minimum ...

I was able to let it work with the following: my confusion was due (I guess it's usual) to my bad understanding of MainLoop: I believed it was <always> necessary, and I didnt know where to put it.

Instead with DoOneEvent in the right place everything seems ok now...


init();

$mw->bind("KeyPress>",sub {exit});

while(1)
{
    life();
    DoOneEvent();
}

sub life
{
  updatecells();
  showcells();
}

thanks again!
