I have the same problem, since nearly a half year, but nobody was able to help
me. The problem is, that I can not reproduce the phenomenon. I have a table with
20 LookupCombos (Lookup-Queries) and when I update the main-query, sometimes
some of the Lookup-Combos become blank, but never the same and sometimes no
Lookup-Combo become blank. Very strange.
