[pilot-db-list] More feedbacks

[Fab <kr...@bi...>]

	I do have repeted but not systematical crahses when modifying
the names of fields. Crash happens after the box telling the base
needs to be recomputed, and the resulting base miss the changes made.

	The separators (when toggled) of fields disappear starting with
the second row when you scroll down. They reappear starting from the
last record when scrolling up.

	I have a simple script that compute the difference between the
values of one field, current record minus previous record. When the
current is 0, it seems the diff is computed with 65536 instead of 0.
