When I turn on auto generate on heightfields and move any slider related to heightfield settings, the application immediately turns white. Vista shows 'Terragen 2 has stopped working' with a 'Close Program' button. I'm assuming this is some kind of crash. It happens every time.
Version 1.9.99.1 on Quad Core running Vista x86 (32 bit). Let me know if you need more details.
Thanks.
