Good try but no cigar. Swapping table positions in the join from propnum=pocontact to pocontact=propnum did not return results expected.
The new index on groupid did mot change speed. The browse is taking 5.84 now instead of 5.67sec before. I could figure out how you got the FORCE in the query since I used the query builder for the views. I did it from command window but no difference in speed.

good ideas but frustrating!
