>Whoops. Sorry about that. When I click on the column header I attempt to "Index on fieldname to tempidx"

Stop right there!!! [g] Don't, I repeat DON'T use IDX indexes on buffered data! You are only asking for trouble (as I found out the hard way)! If you use IDXs instead of CDXs, your TABLEUPDATE will not work. You'll think it works, but it won't save your changes.
