I have had trouble running a series of simple exact tests.  Whenever my
tables go beyond 2x2 to tables such as the example below, STATA grinds to a
virtual halt.  I waited a half hour before pressing the "break" button.

This is as far as STATA gets before it seems to stop.

I am using STATA v8.2, on a PIII PC with 512mb of RAM running XP
Professional.
