This si the pointer to the source.
in particular check;
/pilot-db/src/design.c
/pilot-db/src/edit.c
granted I don't have the code atm, so these may not be the right directories... Try grepping your root download directory for union and see what it turns up. (in windows, search for files containing union then find it in that text)
All else fails, ***as a last resort***, mail the developer... ask what the structure for the DB records looks like.
btb, waht device do you have, since it is in the older devices sectioN?
