I've never seen this ... if I reply to a post in the newsgroup it
will post it only to newsgroup. Only problem is I might accidentally
hit Reply All because its the required procedure at work for mail ;)
Currently using TB 2.0.0.24.

Some times ago, I wrote a endless pseudo random landscape scroller.
The code is this:

It based on a heightfield with a "Dents"-pattern as a
function to the heightfield. IMO a very easy way, to
generate pseudo random landscapes.

Hope it helps.
