While I was in the UK, I rather hurriedly created at JSR's request a clone of the live titles database for duplicate-entry checking. I ended up doing it at 2am on the night I was leaving, because it was the first chance I got and it was urgent. Not the best time to be working, especially with jetlag and at the end of several long days of work. It turned out that the cloned db did not inherit a number of triggers which were essential to the functioning of the interface. SF reported that drop-down lists were empty of content, although they had items. I've now copied over the triggers on the owners, titles, lawyers and props tables, and I think everything is fixed.
