Sorted it out.  Everything worked fine in the AH Beta, by the way..but I reinstalled all latest video drivers, etc.  It then worked.
Now the strange part.  Every time I run the Beta version, then exit and run the regular AH, the regular AH crashes to desktop when I attempt to run it.  If I restart the computer, I can then run regular AH.  This was no fluke, I can reproduce it at will.  Something left in memory, or a file left by the Beta version maybe?  Did I miss something saying I'm supposed to restart it?
