I posted this as issue 193 on google code. However, as this seems a relatively easy matter, I wonder whether anyone on this list knows how to correct it.
I set up a simple autocomplete field. Then using DB admin... - In old welcome layout it works normally, with a drop-down selection of 10. - In new welcome layout it only displays a single item. I would revert back to the old layout, but that causes other problems. Thanks, D
