Now for something else.
As mentioned earlier 
http://forums.planetside.co.uk/index.php?topic=2793.msg31311#msg31311i had a really strange changing of values happening with the Alpine fractal,but didn't
document it.
Lately i was playing with the Alp frac and it happened again,this time i took a screenshot
and saved the tgd immediately.
The values before:feature scale 3000
                          lead in oct 2
                          smallest scale 100
                          noise oct 8
went to the other tab and changed scale step and stretch factor and switched back
to the first tab:    feature scale 3000
                          lead in oct    822
                          smallest scale  1.#INF
                          noise oct    0
screenshot is attached,if you need the tgd too,let me know.
