You guys are probably right;  I did the calculations on a machine I rarely
use for Stata:
Stata executable
   folder:               C:\Stata8\
   name of file:         wsestata.exe
   currently installed:  30 Jan 2004
Ado-file updates
   folder:               C:\Stata8\ado\updates\
   names of files:       (various)
   currently installed:  14 May 2004
m.p.

More fuel for the fire... As you can see, I'm lazy. BUT, I have the
newer version of tabi (Marcello has the older one) but an older Stata
executable than Tom. My combination gives the right answer.
It looks like the change in the algorithm occurred with the Oct. 6, 
2004 executable.  So, if you have an earlier version, I guess you will 
get the right results, but it may take forever to get them depending 
on the problem.  As was noted in messages a few months ago, the 
improvement in speed is dramatic.
You probably don't need Fisher's exact for a problem like this though!
