Thanks to everyone (Ian, Jørn, Jim, Øystein) who cleared this up for me.  I 
also observed the above bug with my version, but since I didn't realize 
that there were separate seeds for playing and rollouts, I assumed it was 
the same bug.  Additionally, if I go into Options - Dice, the arrows on the 
seed spinner don't work well (and they don't work at all as Øystein notes 
under Options - Rollouts).  If I click up or down, the seed immediately 
changes to 15999999 or 16000000.  Also changes to the playing dice seed 
with the seed spinnner aren't actually retained (similar to Ian's 
observation that changing the seed directly (set seed [seed]) doesn't 
retain the seed.

Finally, when I "show seed" gnubg responds "You cannot show the seed with 
this random number generator."  This is for both Mersenne Twister and 
ANSI.  Is this a bug?

Thanks,
Chris
