I'll install PuTTY, try toybox hg head, and play with them later, see if I can reproduce that segfault. I use the last released tarball of toybox, an old Ubuntu, and a bunch of other terminal proggies. I did not know that PuTTY had been ported to Unix. But as I mentioned, not interested in a bug hunt right now. That will be more appropriate when it's less of a "sandbox for testing the ideas" and more of a "good enough to bother using". Always good to have other terminals for testing though. -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world.
