No! No! No!

Sorry to be so emphatic, David, but I do want to be clear here.

I am not aware of anything at all about differences in INDEXES between FP and VFP!!!

What I was suggesting to Evan was to keep at it because I don't think that 6-7 seconds is reasonable at all in the example he cites. I feel that there is something amiss for sure, but at a loss to explain (given especially the info available).
