Oh hell yes...on 2 different machines no less. One an Athelon 1300, 512 ram, win2k and the other a celeron 700, 512 ram, win2k. Both systems were rebooted after install and each have 32 meg video cards. They have both frozen in 16 bit and 32 bit color modes. The first has froze up 8 times and the second at least 8 times...all in a 4 hour period. The video cards have the latest drivers and latest version of direct x. How do I fell about this......very disappointed ;-( Update: Uninstalled it from the 1300 and put it on a duron 950. It is locking up in firefly render with a 16 meg ATI video card. My Gawd...is SR1 out yet !!!
