I start the installation of build 796 from the downloaded file, and the installation progresses to the small dialog box for drivers. After a few seconds the program (and the whole computer) locks up -- the little clock in the box halts and there's no response to mouse or keyboard inputs. Power-off shutdown of the computer is the only out. Seems pretty obvious a driver conflict of some sort; I was hoping someone might have an idea where to start looking. Thanks!
