Hi Rick,
As I mentioned, when I have fritz using Houdini, and it is analyzing a
game, it takes over the cpu and I can not do anything else because WE9.2
goes silent.
However, if I set we9.2 to use one core and Houdini to use the others,
then I can do other things with my computer because
WE9.2 is able to speak.
My thought is that WE9.2 should during installation instruct the
operating system to give WE9.2 exclusive use of one core; thereby
avoiding silence when other programs hog the cpu.

Good Luck, Manny please help me reach a million clicks by forwarding my
stand-up comedy performance to your friends, or Tweet or Facebook it. **
